Description
San Jose Astronomical Association Imaging Special Interest Group Meeting. May, 21st, 2020. General Discussion and Sharing.
A
Well,
it's
a
35
going
over
time
here
on
the
beginning,
so
I
guess
we
should
begin
welcome
to
the
roll
Imaging
sig
meeting
the
first
of
many.
Hopefully
that
will
be
an
online
web
conference
style.
Imaging
save,
meeting
and
well
I
do
hope
that
we
can
meet
together
in
person
soon
at
least
getting
somebody
to
predict.
The
quays
is
very
attractive
because
we
can
get
presenters
from
very
far
away
and
not
have
to
have
them
travel.
A
So
I
think
this
is
very
fun
thing
for,
for
our
group
to
get
presenters,
we
already
have
a
couple
lined
up.
Gary
Lopez
is
probably
he's
gonna
be
joining
us
next
month
and
anyway
we
are
gonna.
Have
an
open
discussion
tonight,
talk
about
whatever
you
guys
want
to
talk
about.
If
you
want
to
show
us
some
of
your
recent
images
or
talk
about
projects
you've
been
doing,
please
feel
free
and
Glenn
was
gonna.
He
was
gonna
talk
about.
A
It's
been
helping
me
in
the
hobby
too,
as
a
matter
of
fact
I'm
on
the
verge
of
getting
a
3d
printer
myself,
because
it
has
been
so
helpful
to
make
various
things
that
we
need,
and
it's
amazing
that
you
could
just
make
it
in
your
house
now,
instead
of
getting
it
from
precise
parts
and
you
know
putting
an
order
in
and
getting
a
month
later,
maybe
Glenn
you
want
to
talk
about
it.
A
little
bit
yeah.
B
A
B
So
when
I've
got
parts
of
scopes,
exposed
or
I
am
using
a
camera
lens
right
at
the
moment,
and
just
with
that,
a
little
50
millimeter
Orion
guide
scope
to
do
the
guiding
and
somehow
I
lost
the
the
dust
cover
for
that
or
the
lens
cap.
For
that,
so
when
I
went
to
do
you
know
a
new
profile
in
PhD,
I
didn't
have
anything
to
cover
the
the
the
lens
with,
but
you
know,
20
minutes
later
I
had
a
3d
printed
cap
that
fit
right
on
it.
B
So
that's
cool
and,
of
course,
lots
of
threaded
adapters.
/
spacers
for
people
and
myself
using
these
different
threads
listed
here
are
some
of
the
ones
I've
done
and
Paulo
is,
is
working
on
improving
the
the
thread,
library
that
we're
using
and
also
on
figuring
out
how
to
get
the
threads
right.
The
first
time
versus
having
to
print
you
know
four
or
five
different
versions
to
account
for
the
material
expansion
and
whatnot.
B
Then
I've
done.
You
know
some
some
just
essentially
washers
and
did
this
adapter
for
for
Bruce
to
help
get
his
his
camera
adapter
centered
in
his
Raza
11-inch,
and
that's
still
a
work
in
progress.
I
guess
you
know,
mounting
hardware
lots
of
stuff
for
camera
lenses
and
mounting
and
focusing
that
stuff
things
that
connect
to
the
back
of
your
camera
and
form
a
strain
relief.
B
B
Rotator
he's
going
to
have
a
tray
that
he
puts
in
one
one
at
a
time.
So
we
need
something
to
store
those
in
Apollo
designed
a
really
cool
focuser
for
off-axis,
guider,
z',
and
so
I've
got
one
of
those
and
he's
got
one.
We
both
have
the
same
off-axis,
guider,
filter,
wrenches
and
then
for
my
DIY
rotater
project.
There
was
a
bunch
of
stuff,
the
the
gears
and
belts
and
and
the
project
box
and
the
stepper
motor
mount.
C
B
B
So
just
some
of
the
stuff
that
that
I've
done
and
then
I
think
when
I
first
presented
on
on
3d,
printing
and
Astro
many
moons
ago
in
the
PowerPoint
I
did
for
that.
There
were
lots
of
examples
of
designs
of
things,
including
whole
telescopes
that
you
could
download
and
in
3d
print,
so
usually
I,
don't
design
everything
from
scratch.
I'll
just
go
to
thingy,
verse
and
search
for
you
know
whatever
a
lens
cap
or
something
and
then
tweak
it
from
there.
B
B
B
Actually,
spool
is
inside
that
enclosure
as
well,
and
then
I
can't
see
my
camera,
but
if
I
turn
it
a
little
bit
over
here,
Paolo
and
I
both
have
this
FL
Sun
QQ
s,
Delta
printer
and
we're
using
that
for
the
a
si
and
some
of
the
other
materials
and
it's
a
little
faster
and
it's
you
know
a
different
style
of
printer,
but
it
has.
It
has
its
advantages
and
disadvantages:
okay:
okay,
trying
to
put
my
camera
back
yeah,
okay,
yeah
thanks.
E
E
B
Yeah,
so
the
the
FL
Sun
QQ
s
is
not
gonna.
Do
like
the
the
nylon
and
even
the
I.
Think
for
the
a
si
Paolo
is
like
enclosed
his
I'm
still
doing
it
unenclosed,
but
it's
fairly
versatile
that
way,
and
then
the
the
Qi
di
xmax
can
do
pretty
much
everything
you
know
it
can
it
can
because
it
they
actually
have
they
give
you
two
extruders
two
hot
ends,
one
for
higher
temperature
stuff
and
one
for
lower
temperature
stuff.
So
that's
one
reason
why
I
have
two
printers
is
I.
A
B
F
I
was
gonna,
ask:
are
there
any
concerns
about
the
longevity
of
like
the
threads
or
the
strengths
of
that
stuff?
It
seems
like
you
know
that
they're
pretty
fine
parts,
and
you
know
the
kind
of
thing
that
you
thread
it
in
once
and
never
worry
about
it
or,
if
you're
taking
it
out,
maybe
it
breaks
or
anything
so.
B
Most
of
the
things
that
I've
done
as
threaded
adaptors
have
been
prototypes.
So
it's
like
you,
you
need
something,
and
so
you
print
it
up
and
use
it
while
you're
waiting
for
the
metal
part
to
to
arrive
I,
know
I,
think
Paulo.
You
know,
I
made
him
a
adapter
that
goes
from
his
short
tube
80.
All
the
way
down
to
his
his
guide,
scope
and
I.
B
Think
he's
had
that
outside
for
for
quite
a
while,
but
you
know
there's
bits
and
pieces
of
not
threaded
adapters,
but
you
know
my
whole
rotator
and
and
stuff
is
been
outside
for
months
now
and
it's
been
fine,
so
yeah
I
guess
you
know
kind
of
use
it
your
own
risk
kind
of
thing.
But
but
you
know
we
keep
learning
about
more
about
the
materials
and
and
making
sure
that
they're,
UV
resistant
and
and
all
that
stuff,
so
I
think
it's
probably
just
a
good
idea.
B
B
You
know
flip
the
the
shoulder
strap
up
over
the
the
guide
scope
or
something
so
that
if,
if
something
does
come
loose,
you
know
at
least
your
camera
doesn't
hit
the
ground
and
I
think
if
I
was
and
I'm,
probably
given
Bruce
this
advice,
you
know
yeah
here's
this
adapter,
you
asked
me
to
make
for
your
multi-thousand
dollar
CCD
camera
right,
so
put
some
string
or
something
just
in
case
this
thing
dissolves
in
an
instant
or
something
you
know
just
in
case,
so
that
that
would
be
the
just
an
extra
safety
measure.
I
guess
all.
A
B
Yeah
well,
this
is
this
is
about
how
to
make
things
stronger
without
printing
them
stronger,
because
you
know
you
can
print
them
completely
solid
or
you
can
print
them
with
with
what's
called
infill.
That
could
be,
you
know
anywhere
from
five
percent
to
two
solid,
but
that
takes
a
long
time,
so
people
have
been
experimenting
with
injecting
some
kind
of
plastic
inside
the
3d
printed
part
to
make
it
stronger.
So
two
candidates
are
hot
glue
and
epoxy
in
the
hot
glue
is
a
cheap
material
cheaper
than
the
3d
filament.
B
So
that
was
something
we
were
it's
but
I
wouldn't
say
it's
successful.
Yet
this
is
a
part
here
that
I
had
to
drill
multiple
holes
in
it's
a
lens
filter.
A
filter,
wrench
and
I
tried
to
get
the
hot
glue
in
there
and
it
didn't.
You
know
it
works
for
a
while,
but
then
the
glue
cools
off
so
we're
still
trying
to
figure
that
out
but
yeah.
A
I
I
started
this
thread
on
cloudy
nights.
It
was
based
on
a
thread
that
was
done
by
another
guy
who
goes
by
the
candle,
a
peashooter
and
he's
a
Rosalyn
or
even
terraza
eight,
and
he
and
other
people
that
have
roses
have
noticed
that
the
Naza
has
a
collar
that
you
use
to
lock
down
the
camera.
Maybe
I
should
show
you
guys
that
see.
Where
is
my
there?
We
go
okay,
so.
A
And
it
goes
over
the
the
plate
that
is
attached
to
your
extensions
that
are
attached
to
your
camera
up
against
them
and
they
go
on
the
front
of
the
Raza
and
basically
it
attaches
the
plate.
That
holds
everything,
including
the
camera,
to
the
front
of
rosna
the
Raza.
Unlike
most
telescopes,
it's
it's
similar
to
a
hyper
star.
Your
camera
goes
on
the
front
and
it
makes
it
an
extremely
fast
setup.
G
D
A
A
F
A
A
This
thing
right
here,
which
contains
some
corrector
lenses,
and
it's
flattens
things
out
like
a
schmuck
camera.
If
you're
familiar
wish
to
make
cameras,
they're
extremely
fast,
I
think
they
did,
they
made
them
back
in
the
70s.
The
only
problem
was
that
they
required
a
curved
piece
of
film
inside
the
camera
in
order
to
work
and
the
rods
line
so
that
it
could
be
similar
to
a
hyper
star
extremely
fast.
It
has
the
camera
on
the
front
rather
than
at
the
back
of
the
telescope
and
the
the
design
of
the
row.
A
A
I
was
seeing
tilt
on
one
side
and
it
was
pretty
flat
on
the
rest.
Part
of
that
is
due
to
the
camera
distance,
but
also
part
of
it
was
due
to
the
camera
not
being
Center,
and
we
were
able
to
scale
up
a
ring
that
they
had
designed
for
the
razza
eight
and
use
it
on
my
raza,
11
and
so
Glenn
was
able
to
print
it
up
for
me
and
I
was
able
to
every
time
I
put
the
camera
in
there.
A
As
you
thread
down
that
collar,
you
feel
that
it's
really
centering,
it's
not,
it
doesn't
have
any
slop
around
it
and
it
flattened
things
out.
A
lot
and
I
still
have
a
lot
of
tweaking
to
do,
but
I'm
really
happy
with
the
way
that
it
worked,
and
you
know
I've
had
him
make
me
some
other
adapters
and
Paulo,
maybe
a
nice
adapter
recently.
So
basically,
what
I'm
saying
is
the
3d
printer
is
an
amazing
tool
for
astrophotographers.
A
I
J
Actually,
I've
had
the
usual,
run-of-the-mill
cable
issues.
You
know
I
have
been
used,
navarch
11
for
samples
now,
and
I
have
encountered
some
problem
with
the
telescope
which
are
similar
to
what
Bruce
is
going
through,
but
they're
also
different
officer
up
somewhat
of
a
different
take
on
the
issue
with
the
vasa.
The
retained
ring
that
who's
talks
about
to
tighten
down.
It's
called
a
lock
collar
and
it's
about
4g
diameter
and
screw
down
on
to
the
broker,
and
it
requires
a
fair
amount
of
torque
to
hold
the
cameras
in
place.
J
If
you
tighten
it
up
too
much
and
has
happened
to
me,
the
collar
can
call
against
the
de
veau
corrector
cesta,
taking
a
trip
down
to
Torrance
California,
where
they
could.
They
could
take
the
part
recalibrate
the
entire
telescope
and
send
it
act
me
on
their
dime.
I
have
come
up
with
a
design
that,
instead
of
a
lock
collar
having
to
torque
down,
wrote
the
corrector
in
order
to
hold
camera.
J
Simply
in
place
that's
putting
a
severe
amount
of
torque
on
a
something
is
not
engineered
to
handle
it
such
that
the
whole
colo
corrector
can
spin
inside
the
snip
plate,
which
is
probably
not
a
good
thing.
I
have
figured
out
a
way
to
put
instead
lock
collar
and
pressing
I'm
going
to
be
able
to
put
block
all
our
intention,
and
it
will
require
much
less
torque
to
do
that
and
to
hold
the
camera
assembly
very
rudely
against
intention
against
the
lock
collar.
So
it
won't
be
a
lock
all.
It
will
be.
J
A
tension
ring
so
I'm
trying
to
figure
out
how
to
get
this
made
a
happy
day
out
of
metal.
A
plastic
won't
won't,
won't
be
able
to
handle
the
stresses
that
I
may
just
see
if
pretty,
that
precise
parts
can
can
actually
look
at
what
I
want
to
do
and
see
if
they
can
make
it.
It's
not
quite
fits
in
within
their
computer-aided
design
on
parameters
that
they
have
on
their
website.
So
it's
going
to
be
a
little
bit
more
cuts,
as
a
Buddha
saw.
J
J
As
as
an
issue,
however,
I've
been
using
a
qhy
68c,
an
color
camera
and
I
have
come
to
the
conclusion
that
it
is
unsuitable
to
be
used
with
the
Rasta
bhagavata
and
the
camera
is
that
the
poses
bare
earth
as
a
a
cone
of
about
I
calculated
our
boss.
Twenty
six
degrees
angle
coming
in
now,
the
advertising
material
for
the
camera
shows
that
they
say
is
fully
multi-coated.
J
J
Anti-Reflective
coating,
so
what
that
means
is
that
when
you
have
very
steep
angle
coming
in
the
life
out
those
inside
the
attack
in
chamber,
it's
the
sensor
that
light
now
becomes
a
principle
of
Huygens
becomes
a
life
source.
It
now
reflects
off
the
back
of
the
cub
laughs
right
in
front
of
the
sensor
and
reflects
back
to
the
center,
thereby
creating
a
halo
that,
in
any
kind
of
medium
bright
star,
is
about
90
pixels
in
diameter.
J
It
is
pervasive,
it
happens
every
time.
It
is
very
obvious
that
when
you
see
a
globe
when,
when
you,
if
you
brighten
and
pixel
size,
you
see
these
persons
that
are
just
closed,
I
acted
derived
an
equation
that
will
calculate
how
wide
this
globe
is,
depending
on
the
F
number.
It's
only
dependent
on
yes
number,
so
that
that
equation
also
showed
me
that
if
I
were
to
use
a
used
camera
on
about
it
at
four
point
five
five
optical
system,
it
should
work
great.
So
that
is
what
I'm
doing
now.
J
So
it's
very
cheap
to
build,
and
it's
just
a
Newtonian
six
inch,
but
already
the
test
shots
show
that
I
do
not
have
a
discernible
hair.
You
know
look
who
any
clothes
show
about
that
that
my
new
payload
does
pretty
much
my
calculation
and
how
big
it
would
be.
So
how
is
actually
they
able
to
calculate
the
space
between
the
serve
and
the
cover
pass
on?
The
sensor
itself
is
in
the
sama
tree.
J
I
used
to
be
a
stir,
bear
so
York,
oceans
and
tangents,
and
all
that
good
stuff
come
in
handy
on
that
kind
of
thing.
So
that's
where
I'm
at
now,
I
have
qh
2080
attach
two
sixes
utonium,
which
is
on
a
MX
plus
mallet,
so
I've
been
having
fun.
You
know
dialing,
that
telescope
in
I'm
ready
to
give
it
a
pull.
Moving
to
later
on
us
just
getting
progresses
any
questions.
F
B
F
A
House,
you
know
actually
I
ran
across
a
machinist
I
think
it's
Michaels
machinists
shop
in
San,
Jose
and
I
had
a
serious
11
pound
weight
weight
that
I
wanted
to
use
with
my
Atlas
Pro
and
it
needed
to
be
bored
out
a
little
bit
and
he
was
more
than
happy
to
help
me
out.
As
a
matter
of
fact,
he
insisted
not
to
bill
me
for
any
of
the
work
he
would
not
take
money.
A
J
A
J
E
Like
a
pyramid
scheme
to
me,
not
actually,
if
you
could
pass
the
ground
rules,
because
I
still
need
an
adapter
to
put
my
ten
micron
mounds
on
my
Astrophysics
ego,
yeah
and
I
could
never
figure
out
it
is
it's
not
that
difficult
to
make?
It
doesn't
need
to
be
super
precise.
It's
just
a
solid
block
of
steel
of
metal
that
you
basically
meet
and
then
I
could
never
find
a
way
how
to
do
this
myself.
You
definitely
can't
really
printed
so
having
something
like
this
would
be
awesome
here
locally
with
his
number
up
cool.
E
D
A
A
D
B
H
B
B
B
Here,
it's
a
little
harder
to
see,
but-
and
so
I
was
trying
to
figure
out
how
to
deal
with
that
and
I
came
up
with
something
that
works
pretty
good
and
it's
pretty
simple
and
it's
a
variation
of
you
know,
selection
modifications
that
I
was
taught
to
do
by
somebody
on
the
internet.
I
have
no
idea
who,
but
what
I
ended
up
doing
was
just
drawing
you
know
a
line
around
the
transition
making
a
making
a
selection
here.
B
So
this
is
the
expanded
and
feathered
selection
and
then
I
just
changed
the
levels
until
you
know
it
looks
about
the
same
and
then,
if
I
remove
the
selection,
it's
not
too
bad.
Yeah
I
mean
now
that
you
know
where
the
where
it
was.
You
can
kind
of
see,
there's
an
artifact
there,
but
that's
that's
what
I
did
on
this
image
that
eventually
turned
into
this
one,
so
just
wanted
to
share
that
little
technique.
G
E
D
D
Where
is
that
again
present
now
yeah
there's
a
big
problem
with
the
image
the
the
problem
is
that
I
did
this
and
I
was
really
happy
with
it?
Can
you
guys
see
the
the
galaxy
yep
yep
I
was
really
happy
with
this
and
I
shared
it
with
Francesco,
and
he
process
it
better
than
me.
So
I
wasn't
thrilled
with
that.
But
what
are
you
gonna
do
right,
but
I
was
happy
with
the
image
anyway.
D
So
and
in
my
goal
but
I
don't
know
I
have
this
kind
of
you
know,
I,
don't
know,
I
can't
get
anything
done
when
I'm
all
at
home,
with
this
COBIT
thing
so,
but
my
goal
is
Francesco
shared
his
processing
techniques
and
I'm
gonna
try
to
copy
him
and
see
if
I
can
get
it
to
where
it
is,
but
even
the
way
it
currently
is
wasn't
so
I
guess
what
I
liked
about
it
was.
You
know
I
thought
my
nose
down
there
at
the
bottom
is
a
pretty
dim.
D
Gal
I
mean
small
galaxies,
but
yet
my
4-inch
scope,
it
worked.
You
know.
There's
plenty
of
detail,
looks
nice
on
it:
sort
of
a
nice
composition
with
those
smaller
red
and
red
and
blue
star
on
top
and
whatever
galaxy.
That
is
there
lots
of
little
galaxies
anyway.
So,
like
I,
said,
I
was
happy
with
the
the
image
and
at
this
scale
it
looks
okay,
you
blow
if
you
zoom
into
it
it's
on
my
astro
bin.
D
C
D
A
A
J
F
A
A
C
K
C
And
we're
back
okay,
let
me
expand
it
to
the
whole
screen,
so
you
can
only
see
that
yeah.
Is
it
still
there
showing
to
you?
Yes,
okay,
I'm,
never
sure
when
it's
a
full
screen.
So
anyway,
this
the
heist
data
and
my
processing-
and
there
is
a
project
that
I'm
currently
working
on
and
it's
NGC
903
I'll
be
taking
two
more
hours
tonight,
but
for
now
I
have
this.
C
F
C
C
So
thanks
to
rob
the
who
prepared
the
the
plugin
for
p8
for
peace
inside
I
can
do
it
directly
from
the
application,
instead
of
doing
it
from
with
a
command-line
tool,
and
we
also
we
do
some
experiments.
We
also
found
how
to
run
it
on
Mac
OS
without
even
on
Catalina,
without
problems,
but
yet
there's
still
work
to
do
there
on
on
once
part
I.
C
Think
that's,
since
the
last
time
I
saw
all
of
you
guys,
I,
probably
also
processed
this
one.
This
is
this
is
the
third,
the
lesser-known
of
the
lesser-known
of
the
bright
nebula
in
you
know
Riga.
So
this
is
I,
see
four
one
seven.
So,
let's
turn
on
then
I
see
four
or
five
and
I
see
four
ten,
the
flaming
star
nebula
and
the
tadpoles,
but
still
it's
a
I
think
the
nickname
for
this
one
is
the
fly
and
spider
the
this
being
the
spider,
and
this
one
is
supposed
to
be
the
fly.
C
This
is
ten
hours,
there's
lots
of
noise
because
of
the
bordel
seven
sky.
So
we
have
to
do
what
we
have
to
do
in
this
moment,
but
I
had
in
the
past
had
better
results
from
these
skies.
I'm
happy
in
particular
about
my
my
monkey
head
from
February
from
the
same
same
sky.
It's
I,
think
six
hours
and
a
half
but
there's
much
less
noise.
C
C
That's
it
and
right
now,
as
you
can
see,
can
you
see
white
Peaks
inside
yes,
yeah
right
now,
I
was
trying
to
find
the
right
weight
expression
for
the
127
frames
that
I
have
so
far
collected
about
NGC,
903
and
tonight,
with
with
any
luck,
I
will
have
30
more
and
probably
I
will
call
it
done
because
after
that,
there's
next
the
next
day
with
the
clear
skies
will
there
should
there
will
be
a
pretty
bright
moon.
So
it's
that's
probably
it
for
this
month.
For
me,.
C
So
they
typically
render
a
high-resolution
image
and
they
scale
it
down
so
that
your
display,
if
it's
capable
of
high
DPI,
renders
a
much
better
image
and
I
have
a
complaint
about
this
to
Salvatore
to
no
avail.
So
at
some
point,
I
decided
to
to
take
the
matter
in
matter
in
my
hands
and
I
first
developed
an
extension
for
Safari
for
one
for
Chrome
and
one
for
Firefox.
That
would
replace
the
image
with
a
high
resolution
counterpart
on
the
fly
on
client
side
only
and
the
next.
C
At
that
point,
I
extended
to
Salvatore,
saying,
hey,
take
a
look
at
how
much
better
your
site
could
be,
and
he
actually
liked
it.
And
so
he
asked
me
if
I
could
take
a
look
at
the
source
code,
so
that
I
could
be
more
effective
in
doing
that.
It's
still
a
client-side
substitution
of
the
image,
but
there
are
a
number
of
hints
that
the
server
sends
to
the
client,
the
web
browser
in
this
case,
to
do
the
substitution.
C
So
if
you
notice
in
the
last
10
days
that
the
apparent
quality
of
the
images
shown
in
Astra
bean
in
the
images
would
what
he
calls,
the
technical
card
has
improved.
It's
probably
because
of
the
code
contribution
that
I
sent
him
ten
days
ago,
and
he
he
reviewed
it.
He
asked
me
for
some
modifications
and
ultimately
accepted
and
rolled
it
out
last
yea
not
last
week
and
by
the
previous
one.
M
I
A
C
The
reason
for
that
is
that
when
you
hover
the
mouse,
a
strobe
in
shows
you
the
the
plate
solve
the
version
with
the
annotations.
Okay,
even
if
you
don't
do
it
it
best.
Urbina
still
shows
you
a
pre-prepared
version
that
is
supposed
to
have
the
overlays
and
that
pre-prepared
version
has
low
resolution,
no
matter
what
I
can
do.
There's
no
high
resolution
version
of
that
image,
so
I
cannot
do
the
trick
to
substitute
the
only
solution
would
be
so
you
can,
if
you
have
an
ultimate
subscription.
C
You
know
that
there's
new
level
and
you
do
the
advanced
plate
solving.
Then
it's
actually
an
SVG
overlay
and
it
retains
the
same
quality
of
the
image.
But
if
you
use
the
old-style
astrometry
dotnet
and
overlay,
then
if
you
should
probably
make
some
changes
in
the
way
the
the
image
is
processed
after
its
returned
from
from
astronomy
trade
of
that.
L
A
C
N
C
A
Did
I
haven't
had
a
chance
to
look
at
it
too
much
so?
Okay,
so
I,
just
I
brought
up
one
of
your
I
brought
up
your
pac-man
yeah
from
a
couple
years
ago
and
and
as
the
technical
card
came
into
as
it
it
filled
in
mercury.
The
image
looked
soft
right.
Yes,
here
a
couple
seconds,
it
filled
in
with
the
higher
resolution
image
so
yeah.
C
G
Helios
book
we're
like
two
T's
two
parts
to
it:
I
started
looking
at
the
reference
section,
cuz
I
thought
it
was
pretty
useful
that
kind
of
as
manual
for
a
lot
of
the
functions
get
in
the
book,
because
I
don't
think
pics
on
site
has
an
official
manual
yeah
right,
I
haven't
I
mean
look
at
the
other
part
I
guess
it
just
has
more
general
processing
steps,
but
so
price
it
looks
pretty
well
written
I
know.
Did
you
have
on
it?
I.
H
H
But
for
one
thing
he
takes
three
separate
passes
at
the
at
teaching
you
the
first
one
is,
is
for
beginners
and
he
keeps
things
simple
and
depends
on
the
defaults
and
pushes
you
right
through
it,
and
then
he
comes
back
in
the
second
pass
and
goes
into
more
detail.
So
you
don't
have
to
read
all
800
pages.
Just
get
going.
I
brought
a
picture
I'm
working
on
a
picture.
Okay,
I
can
no
I
didn't
when
I
went
to
find
the
latest
version
of
it.
H
I
couldn't
come
up
with
it,
but
I
will
bring
it
up
if
I
can-
and
this
is
this
is
like
from
two
days
ago-
I've
read
a
better
run
now,
but
this
story
is
the
same:
let's
see
if
this
works,
can
you
see
this
picture
it's
starting
this
year?
Yes,
it's
coming
up:
yep,
okay,
okay,
a
couple
of
weeks
ago,
hi
posted
something
about
this
comet
Atlas
and
I
thought
that
sounds
interesting.
I
looked
it
up
and
I
then
made
a
point
of
getting
out
to
shoot
it.
H
H
The
field
of
view
is
three
degrees
by
four
and
a
half
degrees
and
I
was
processing
this
on
a
laptop
which
was
extremely
slow
and
painful.
So
I
got
the
idea.
Well
when
I'm
all
done
with
this
I'm
gonna
crop
this
way
down.
So
I
said
why
not
crop
it
before
wasting
a
lot
of
time
on
the
computer,
so
I
used
the
crop
process
and
I
went
through
and
cropped
63
images
by
a
factor
of
about
12
and
that
speeded
up
everything
by
a
factor
of
12.
H
H
Was
done
it
first
in
pix
insight
through
the
weighted
batch
processing
and
a
couple
of
more
processes
after
that,
and
then
I
took
it
to
photoshop
and
and
and
made
this
image
that
this
is
aligned
on
the
stars
and
so
that
what
you
see
there
for
the
comet
is
two
hours
of
movement
of
the
comet
of
all
blurred
together,
there's
another
picture:
if
I
can
figure
out
how
to
bring
it
up,
I
have
no
idea
what
to
do
here.
We
push
escape
it
just
see
if
I
can
know.
H
H
C
F
H
Yes,
you
see
a
picture.
Yes,
we
do.
You
see
the
comic
yes,
this
I
used
the
pics
insight
process,
comet
alignment
to
align
on
the
comic,
and
you
can
see
now
the
Stars
or
streets.
You
take
your
images
that
are
aligned
on
the
Stars
and
use
those
as
input
to
comet
alignment,
and
you
click
on
the
first
image
and
the
first
image
in
the
sequence,
time
wise
and
use
your
mouse
to
tell
the
process
exactly
where
the
center
of
the
head
of
the
comet
is.
H
Then
you
do
that
again
with
the
last
image
in
the
time
sequence
and
that
comet
aligned
process
uses
the
times
recorded
in
each
image
to
interpolate,
where
between
the
position
of
the
first
image
and
the
position
of
the
last
image,
it
uses
that
to
interpolate
to
figure
out
where
that
image,
how
much
it
should
be
shifted,
and
so
this
is
what
the
what
a
comet
actually
looks
like
without
the
blur.
Unfortunately,
the
stars
have
learned.
This
is
a
double
challenge.
H
H
When
I
get
this
all
when
I
finally
finish,
this
processing
I'll
show
it
with
round
stars
in
the
true
image
of
the
comet.
This
was
you
know,
we're
locked
down
now
and
I
can't
go
to
a
dark
site
I
where
I
live
in
order
to
see
the
northern
part
of
the
sky
to
see
north
and
all
I
have
to
go
out
to
the
driveway.
I
can
see
three
streetlights
from
my
driveway
and
I
live
in
Menlo
Park.
The
sky
is,
of
course
awful.
But
what
are
you
going
to
do?
H
I
said
it
would
be
better
just
to
if
nothing
else,
for
practice
just
to
go
through
the
motions
of
taking
a
picture,
even
in
a
lousy
sky,
and
maybe,
if
you
get
enough
images,
maybe
you'll
get
a
decent
image.
So
I
had
altogether
about
90
minutes
of
exposures
and
it's
it's
a
chance
to
learn
the
how
to
use
the
rig
and
it's
a
chance
to
learn
how
to
use
fix
in
sight.
So
it's
been
a
good
experience
and
I'll
tell
you
more
about
it.
Next,
one.
H
Yes,
I've
read
the
chapter
and
I've
read
two
or
three
other
descriptions
of
how
to
do
this.
It's
just
a
matter
of
actually
mastering
it.
This
picture
here
is,
is
one
of
my
early
attempts
to
eliminate
the
stars
and
I
have
used
in
addition
to
having
already
cropped
this
down
to
speed
things
up.
I
also
can
make
a
region
of
interest
that
Inc
just
includes
a
small
part
of
this
around
the
comet
and
a
few
of
these
star.
H
H
All
the
time
and
I
have
just
installed
today,
solid-state
drive,
which
about
so
I'm
up
to
about
two
and
a
half
times
the
speed
of
my
laptop
and
I've
got
32
gigabytes
of
RAM
coming
on
Thursday,
so
I
will
soon
be
speeding
along
and
I
love
the
new
book.
But
it's
still
a
challenge
for
a
beginner
to
to
work
through
this
and.
C
A
H
A
G
G
Let's
see
yeah,
you
guys
see
this
all
right,
so
I've
been
trying
out
night
vision,
night
vision,
tech
cool.
So
this
is
a
it's.
It's
a
it's
called
a
mod
3
seed
mount
and
it's
made
by
a
B
night
vision,
and
it's
right
here
in
the
middle
between
there's
a
there's,
a
Sony
camera
here
on
one
end
and
then
there's
a
lens
on
the
other
end
and
for
those
who
aren't
familiar
with
night
vision.
What
it
does
is
it
takes
the
incoming
photons
and
then
it
multiplies
it
by
I.
G
G
Think
in
the
front
of
this
is
a
seamount
which
it's
not
something
we
use
and
astronomy,
but
you
can
convert
from
the
see
threads
to
like
a
two
inch
adapter
and
put
it
into
the
focus
sermon
of
a
telescope,
or
you
can
there's
other
adapters
to
like
here.
I.
Have
it
directly
connected
to
a
Nikon
lens,
so
it's
the
lens
I
think
is
180
millimeter
focal
length,
there's
an
F
2.8.
G
So
it's
basically
like
a
64
millimetre
refractor
operating
at
F
2.8.
So
the
image
pin
you
know
because
it's
it's
basically
a
real-time
view,
so
there's
no
like
long
exposure
of
any
kind,
so
you
want
to
be
able
to
gather
as
much
light
as
possible.
So
having
like
a
fast
focal
ratio
is
a
big
advantage.
You
know
so,
like
f,
you
know,
F,
for
something
or
under
you
can
really
start
to
see.
Nebula
you
can
you
know
in
a
in
the
bright
suburbs.
G
You
know,
I'll
show
a
photo
in
a
moment,
but
I
was
able
to
get
the
rosette
nebula
to
show
up
pretty
well,
it's
quite
large
in
the
sky.
Actually,
it's
really
amazing,
looking
at
it
through,
even
through
at
1x,
without
a
lens,
it
looks
massive
like
I
think
it
feels
like
it's
larger
than
the
full
balloon
I'm
pretty
easy
to
find
it
just
by
scanning
it
around.
Remember
you're,
getting
kind
of
almost
like
a
real-time
view.
There's
no
almost
no
lag,
because
it's
something
that
the
military
would
use.
G
G
G
There's
some
adapters
where
you
can
hook
the
lens
up
to
the
back
side,
but
there's
also
a
lot
of
people
used
like
smartphones
to
take
photos
and
those
work.
Amazingly.
Well,
you
can
get
like
a
standard,
digi
scoping,
smartphone
adapter
to
just
try
to
grip
the
the
head
of
the
the
eyepiece,
and
then
they
just
position
your
phone
correctly
and
and
there's
there's
some
apps
out
there.
That
will
that
will.
Let
you
like
do
a
slightly
longer
exposure
on
your
phone.
G
G
Sun
I'm
impressed
that
I'm
able
to
see
it
even
oh
and
I,
and
another
thing
is
I:
have
an
HP
h,
a
filter
in
the
imaging
train,
I
think
it's
a
seven
nanometer
a
K
filter
and
that's
required
to
bring
this
out
without
it.
You
would
definitely
lose
this
object
to
for
the
bright
skies
so
for
and
then
this
is
probably
if
there's
information
here.
G
Okay,
so
it
was
point
I
started-
was
two
seconds
at
five
point:
six.
Seventy
millimeter
focal
length
on
my
Sony
camera
and
ISO
3200
I
shrunk
it
down
to
a
smaller
size,
just
like.
If
for
easier
sharing
but
yeah.
That's
that's
what
my
Sony
F
five
point.
Six
lens
I'm
sure
like
smartphones,
can
shoot
a
little
bit
faster
volker
ation
that
so
that's
this
two-second
exposure
might
end
up
being
more.
Like
like
a
quarter
second
or
something.
G
G
Globulars
resolved
really
well
almost
likes
photographs
and
I've
tried.
Let's
see,
galaxies
are
a
little
bit
harder
because
they
they
tend
to.
They
don't
benefit
as
much
from
the
filters
I
think
maybe
in
darker
skies
galaxies
might
look
really
nice,
like
you're
in
51
or
in
with
101,
like
maybe
that
spiral
structure
but
I.
Think
in
brighter
skies
you
can.
You
can
see
a
lot
of
different
emission
nebulae
with
with
the
right
H
a
filters
and,
and
then
with
and
just
like
general
stargazing
and
put
on
a
long
pass,
filter,
I.
G
Think
60,
685
nanometers
is
what's
recommended
so
that
basically
cuts
out
like
the
vast
majority
of
the
city
lights
and
then
you
know
gives
you
everything
kind
of
in
the
near-infrared,
which
it
still
is
quite
a
lot.
You
can
see,
like
you
know,
probably
all
the
open
clusters-
Messier
globulars,
will
probably
come
out
really
well
so
I
have
a
couple
other
things
to
show.
This
is
NGC,
4,
4
and
I.
Think
it's.
It
might
be.
A
southern
hemisphere.
Object
I
have
to
check,
but
I
I
can
capture
this
myself.
G
I
got
pretty
generous
amount
of
credits
and
then
once
I
gave
them
some
feedback
about
how
that
how
I
felt
the
tool
work
and
they
gave
me
even
more
credits,
so
I
ended
up
getting
like
a
good,
5
or
6
images
out
of
it
and
I've
been
processing
that,
while
we're
in
quarantine
but
yeah,
this
might
have
been
done
with
the
I'm
thinking.
It
was
a
Ricci
Creighton
with.
Maybe
that's
why
there's
these
diffraction
patterns.
G
But
yeah
they
have
telescopes
them,
some
pretty
dark
skies
and
like
Chile
and
elsewhere,
high
altitude.
So
you
so
I
think
that
pricing
is
quite
expensive
in
that
it's
something
like
probably
comes
out
to
something
like
a
dollar
a
minute
for
their
cheapest
cokes
and
then
like
three
dollars
a
minute
for
some
of
the
higher
end
stuff.
So
you're
looking
at
a
you
know
a
couple
hundred
dollars
for
like
an
hour
of
exposure,
but
since
you're
in
really
dark
skies
you
can
get
pretty
good
quality
but
yeah.
G
If
you
participate
in
the
beta
program,
you
know
you'll
get.
You
know
four
or
five
images
about
a
bit
and
then
let's
see
it
one
more.
This
is
the
the
dark,
doodad
nebula,
so
I
think
one
of
the
things
I
wanted
to
try
and
darker
skies
were
like
dark
nebulae.
So
those
are
almost
impossible
and
bright
skies.
G
G
A
You
know
I
was
down
at
pinnacles
a
couple
years
ago
and
somebody
did
have
one
set
up
and
it
was
pretty
pretty
cool
I
work
with
a
guy
who
uses
it
a
lot,
but
not
for
astronomy,
just
like
Stu
he's
kind
of
like
a
paramilitary
type,
but
he
does
have
some
night-vision
stuff
and
he
knows
what
I
do
for
my
hobby
in
and
he
was
recommending
that
I
check
it
out
and
I
haven't
had
a
chance
to
do
anything
lately
with
it.
But
he
was
saying
that
they
have
some
full-color
night
vision.
A
G
Phonetic
they
have,
you
can
get
them.
You
can
get
like
green
phosphor
or
white
phosphorus,
so
I
think
mines
white,
which
actually
is
more
of
a
kind
of
like
a
dull
blue
I,
think
that
I
think
that
white
ones
are
a
little
bit.
Pricier
they're
lost
a
little
more
popular,
especially
for
astronomy,
I,
think
looking
at
a
green
one.
Maybe
that
can
kind
of
saturate
your
cones
of
that
color.
G
After
a
little
while,
but
I
thought
I
had
the
chance
to
try
out
one
of
these
a
few
months
back
and
you
can
definitely
put
I
created
a
color
image
out
of
one
and
by
putting
RGB
filters
somewhere
in
the
imaging
path
like
but
I
guess
before
you
get
to
the
night
vision
device,
and
then
you
convert
your
images
to
monochrome.
You
know
you
shoot
RGB
convert
to
monochrome,
and
then
you
do
your
standard
integration.
G
G
You
can
probably
do
narrowband
with
really
short
exposures,
provided
your
camera
is
sensitive
enough
like
Oh,
like
I,
did
the
rosette
there
with
a
fraction
of
a
second
and
but
I,
think
I
might
have
to
set
up
some
kind
of
manual
filter
wheel
or
something
so
you
don't
have
to
break
apart.
The
imaging
train
every
time
you're
doing
that,
but
it's
possible
like
with
the
art,
DB
filters,
I,
don't
know
if
there's
a
way
to
give
it
in
real
time
night
vision
that
would
be
I've,
no
idea
how
that
would
work
right.
F
F
B
B
Just
because
that's
what
was
up
but
as
part
of
the
whole
kovat
thing
you
know,
I've
been
working
with
Jerry
who's,
our
president,
now
of
sja
a
on
you
know
getting
ready
to
do
virtual
star
parties,
so
we
are
figuring
out
how
you
know
we
could
the
imaging
side
of
the
house
could
could
help
by
showing
images
while
the
visual
observers
host
the
star
parties
the
way
they
they
normally
do.
So
that's
what
we
been
doing
in
and
Bruce
and
I
have
both
done.
B
Some
live
stacking
in
monochrome
and
then,
if
you
have
one
shot
color,
you
can
do
it
in
sharp
cap
and
then
I
figured
out
a
way
with
some
software
called
Astro
toaster,
not
Astro
tortilla,
but
Astro
toaster.
How
to
do
it
using
deep
sky,
stacker
live
and
narrow
band
filters.
So
if
I
can
grab
the
grab.
G
B
B
So
this
color
image
here
of
the
rosette
was
sgp,
just
like
you
would
normally
use
it,
except
that
was
doing
30-second
exposures
and,
in
a
you
know,
round
robin
versus
finished
an
entire
event.
So
it
was,
you
know,
doing
a
jas
203
in
a
repeating
pattern,
and
then
that's
what
this
this
astro
toaster
software
does.
Is
it
keeps
track
of
all
that
and
and
does
three
separate
stacks
using
DSS
live,
and
then
it
assembles
them
all
automatically.
So
this
this
color
image
here
was,
you
know
the
longer
you
do
it
the
better.
B
It
looks,
but
this
was
after
about
seven
minutes
from
you
know,
Slough
to
the
to
this
color
image,
so
that
was
pretty
exciting
to
be
able
to
do
that
that
quickly
and
then
what
you
see
below
it
here
is
just
a
sharp
cap,
live
stack
of
an
H,
a
filter
and
that
that
was
15.
Second
exposures,
so
that
just
a
couple
minutes
after
slowing
to
the
to
the
object,
then
able
to
show
that
to
people
on
a
screen.
B
So
that's
a
way
that
we
can
use
our
traditional
imaging
rigs
to
show
things
rapidly,
as
if
we
had
you
know,
video
camera
or
something.
Instead,
of
course,
you
could
use,
you
could
put
the
camera
in
video
mode,
but
you
know
these
are
ways
of
using
the
narrow
band
filters
in
the
whole,
the
whole
thing
so.
A
B
I
believe
I
didn't
these
are
uncalibrated,
but
I
know
in
sharp
cap
you
can,
you
can
have
darks
and
flats
I
have
to
look
at
astro
toaster
again,
but
I'm
pretty
sure
it
probably
does
have
that
capability,
but
I
don't
know
that
it's
really
needed
just
to
get
something
up
on
the
screen.
The
I
can
look
for
that.
Yeah.
B
B
B
A
B
E
I
G
B
F
Sorry,
my
mic
was
not
muted,
not
too
much
I
have
an
image
I've
been
working
on,
but
it's
on.
My
other
computer
and
I
was
I,
wasn't
ready,
mainly
I've
been
doing
protein
folding
simulations
for
rosetta
at
home
and
death
and
folding
at
home,
and
some
of
you
know
Francesca
messing
around
with
the
Starnet
stuff
and
I.
Don't
know
there
are
ways
to
make
it
work
on
the
latest
version
of
picked
inside
and
the
latest
version
of
Mac
OS,
but
I
guess
the
ball
has
been
in
want
court
for
awhile.
F
F
On
cloudy
nights
was
complaining,
and
then
you
know,
but
you
know,
like
I
said
I.
You
know
we
figured
out
that
if
you,
if
you
build
the
pictures
that
binary
a
certain
way
it
should,
it
should
work.
But
you
know
I
guess
one
is
been
busy
doing
something
and
he
hasn't
really
stood
so
theoretically,
when
he
really
could
the
tech
that
we
hope
will
start
working
again
and.
C
A
E
A
F
Was
one
thing
that
that
I
forgot
to
mention
that
might
fit
in
with
the
photomultiplier
stuff
that
Joe
was
doing,
which
is
I
found
this
app,
which
is
it's
actually
pretty
awful
app
for
the
iPhone
called
milky,
milky,
cam
I,
think
and
it's
essentially
like
the
attacker
live,
so
it
takes
somewhat
longest
images
and
then
aligns
them,
I
guess
internally
and
then
stacked
them.
So
you
sort
of
get
a
real-time
image
out
of
it,
but
the
user
interface
is
terrible
and
it's
I
not
even
sure
I
know
how
to
use
it.
F
I
managed
to
make
an
image
of
a
Ryan
there's
nothing
to
write
home
about,
but
you
know
and
I'm
fairly
certain
that
the
Android
phones
are
way
ahead
on
this
kind
of
night
photography
anyway.
So
I
may
not
be
anything
really
useful,
but
if
you
have
an
iPhone,
it's
something
to
check
out
it's
free,
app,
so
I
guess
we
got
the
lose.
Let's.
F
I
F
F
F
A
I
J
I
D
J
J
Well,
I
got
plenty
of
trees,
but
m101
is
good.
I
have
a
pretty
good
southern
horizon
and
pretty
good
eastern
horizon
and
I'm
pretty
obscured
from
the
north
north
northwest
to
the
north-northeast,
which
was
kind
of
delivered
on
my
parka.
There
blocks
off
the
big
town
in
these
parts
20
miles
away,
so
pretty
much
I
have
pretty
close
to
an
all-sky
view
and
I'm
on
a
ridge
and
but
I'm
shelter.
The
winds,
not
ever
a
problem
here
snow,
can
be
bet.
J
B
Have
to
wait
till
320
for
my
target,
but
using
that
200
millimeter
lens
I'm
going
to
be
trying
this
butterfly
nebula
and
the
Crescent
in
one
frame.
Oh,
that's
nice!
So
we'll
see
how
that
how
that
goes.
But
again,
yeah
I'll
be
looking
for
10
hours
per
filter,
so
this
will
be
the
first
of
several
nights.
B
B
If
you've
got
like
a
canon
lens
and
a
z,
wo
camera,
you
may
be
familiar
with
the
adapter
that
z
wo
makes
that
you
know
has
pieces,
you
can
add
or
subtract
to
account
for
the
filter
wheel
or
no
and
put
a
put
a
two
inch
filter
in,
but
these
guys
have
added
the
electronics
so
that
using
the
you
know
and
hascomb
driver
and
a
USB
cable,
you
can
focus
lips.
You
can
focus
the
lens
using.
B
You
know
the
the
motor
in
the
lens
that
was
intended
for
that.
So
it's
kind
of
cool
and
so
I
gave
these.
These
guys
are
in
Russia
and
they're
brand
new,
but
I
gave
it
a
shot
and
where's
my
email
and
the
very
first
first
flight
got
a
good
got
a
good
V
curve
and
it
seems
to
work
really
well
so
I'm
pleased.
B
E
B
B
B
O
E
B
The
focuser
yeah
yeah
yeah
I'm,
using
it
with
the
filter
wheel,
but
Bruce
and
I
have
determined
that's
going
to
be
part
of
tonight's
imaging.
Is
it
looked
like
I
had
some
coma
and
I
observed
that
when
it
came
to
focus,
it
was
downstream
sort
of
to
the
left
of
the
infinity
mark
on
the
camera.
So
that
probably
is
an
indication
that
the
spacing
isn't
perfect,
so
I
added
a
3d,
printed,
spacer
and
I.
Think
it's
going
to
put
the
put
the
focus
back
on
the
infinity
mark,
we'll
see
here
in
a
minute.
N
A
O
B
B
K
I
N
O
N
O
Quite
talk
now
because
I
I
cannot
show
anything
on
on
the
on
the
PC,
because
both
my
two
PC
I
don't
know
if
they're,
because
they
are
Windows
7
or
whatever
they
were
not
connecting
to
the
meet
and
I
had
to
run
a
little
phone
and
so
sorry
for
the
for
the
the
mass
before
with
mute
and
these
in
the
other,
because
I
simply
downloaded
the
app
on
the
phone
and
connect
with
that.
But
the
adam2
laptop
that
I
had
they
were
continuing
to
ran
and
ran
and
ran
getting
ready
and
nothing.
O
B
O

So
yeah
you,
the
nozzles,
get
clogged
and
if
you're
using
Falana
with
stuff
in
it
like
carbon
fiber
or
it's
a
metal
or
wood
or
something,
then
you
might
need
a
harder
nozzle
made
out
of
a
harder
material,
so
steel
or
even
sapphire
instead
of
brass
but
yeah.
You
just
changed
the
nozzle
they're,
not
that
expensive.
F
I
I
O
Pop
not
directly,
but
through
maker
Maxis.
That
is
a
group
that
is
collecting
that
and
now
we
are
printing
only
that
the
bottom
part,
because
finally,
that
put
together
in
injection
molding,
so
the
top
path
that
they
are
injection
producing
with
injection
molding
and
they're
producing
thousand
a
day.
And
so
we
need
a
lot
of
low
and
part,
because
that
lower
part
is
too
complicated
to
injection
molding
fast
and
so
need
to
be
printed
and
is
going
24
hour.
B
L
B
F
B
E
F
F
F
N
B
B
B
Yeah
I
don't
do
much
with
it,
it
just
the
there's
another
guy
that
runs
the
network
and
he
logs
into
my
computer
and
does
things
and
keeps
it
all
running
and
I.
Just
you
know,
my
job
is
just
to
keep
the
power
on
pretty
much
but
I
had
you
know
all
of
their.
Their
designs
for
everything
are
based
on
CCD
cameras
that
are
no
longer
manufactured
and
hard-to-find
parts
and
everything
so
I
was
bugging
them
to
look
at.
B
You
know
modern
CMOS
cameras
and
USB
connections
and
stuff,
and
so
there
was
some
talk
about
that
and
I
was
offering
my
all
sky
camera
as
one
they.
They
said
they
were
interested
in
the
particular
it's
a
ASI
178
they
were
interested
in,
but
then
we
kind
of
stopped
the
emails
stopped
flowing
so
I'm
not
sure
what
what
happened
with
that
I
had
a.
B
B
B
B
But
I
think
the
covers
off
enough
yeah.
You
switch
windows
here,
stop
presenting
yeah,
so
this
is
actually
I
picked
up.
The
tip
from
from
PJ
is
to
use
an
IR
camera.
Essentially
an
IR
temperature
pointed
at
the
sky
and
I
got
a
little
module
called
a
blips
tonight.
I
just
did
the
same,
damn
screen
again,
sorry
stop
presenting.
B
There
it
is,
anyway,
it's
a
little
module
that
that
you
know,
speaks
USB
and
has
its
own
web
server,
and
it
has
both
an
IR
and
a
ambient
temperature
sensor.
So
I
this
top
part
of
text
here
is
just
their
their
example
web
form,
and
it's
showing
you
here,
the
the
two
temperatures
and
I
added
some
JavaScript
to
do
this
plot.
So
the
the
green
is
the
the
sky
temperature
and
you
know,
I
think
it's.
B
B
It
doesn't
really
have
anything
to
do
with
precipitation,
but
and
I
haven't
taken
it
any
further
in
terms
of
alerting
me,
but
one
thing
it
doesn't:
detect
is
fog,
so
apparently
fog
is
different
than
clouds
in
the
way
it
reacts
in
in
the
IR
and
I
did
some
research
on
how
airports
and
stuff
detect
fog
and
it's
a
little
more
complicated,
it's
using
lasers
and
backscatter,
and
actually
bought
some
parts
to
make
the
because
they're
very
expensive.
These
commercial
fog
detectors
but
I'd
never
finished
that
project.
One
of
my
999
unfinished.
That's
true
imaging
projects.
B
B
B
B
Basically
I
haven't
done
a
lot
of
ask
programming,
so
that's
in
in
c-sharp,
which
I'm
also
not
familiar
with,
but
I
think
I
could
get
that
working
again
and
or
I've
figured
out
how
to
read
my
weather
station
via
RF
and
so
I
bought
a
little
software
controlled
radio
software-defined
radio
I
think
is
the
term
software-defined
receiver
and
I've
found
a
program
online.
Where
you
can
it
understands
my
weather
station
and
can
can
get
get
the
data.
L
F
A
N
K
K
So
not
the
most
stable
thing
in
the
world,
so
I
looked
for
quite
a
while
online
I
couldn't
find
anything
other
than
nylon
tip
screws
that
were
gonna
secure.
The
secure
the
guide
scope,
so
I
asked
Paulo
if
he
could
or
something
together,
because
I
knew
he
had
a
3d
printer.
So
this
is
an
Orion
sixty
millimeter,
kite
scope
and
I.
Don't
know
if
I
can,
if
it'll,
let
me
I,
guess
it
won't.
B
K
K
H
K
O
P
L
O
Few
hours
you
are
because
they're
the
dovetails
for
the
for
the
vehicle
and
I
think
that
was
three
or
four
hour
and
the
two
vertical
support
other
three
or
four
hour
so
totally
I.
Think
then
eight
to
ten
hour.
But
you
know
it's
not
it's
not
a
big
deal
to
launch
the
crane
t
go
to
bed
and
in
the
morning
you
find
the
piece.
O
O
O
You
have
loop
before
these
kind
of
things
variables
and
it
is
very
convenient
when
you
design
the
mechanical
pieces,
because
you
define
variables
so
with
dimension
and
all
your
design
become
parametric.
So
if
you
want
another
of
those
support
that
instead
of
60
millimeters
65
millimeters
for
me,
is
a
two
minutes
job
to
produce
a
new
design.
K
K

The
different
telescope
I
just
might
break
down
and
do
it
with
a
fiction
because
they're
different,
you
know
they
got
different
cone
errors
and
all
that
good
stuff,
okay,
yeah
but
I
think
oh!
This
is
we're
basically
in
the
moon
new
moon
period.
Now
I
I
got
it
so
I
can
take
pictures
so
I'm
going
to
do
that
for
a
while
alrighty.
J
Yeah
I
got
I,
got
a
fair
amount
of
close-up.
Isn't
that
it's
warming
up
now,
so
it's
only
in
the
forties
and
high
30s.
Everybody
doesn't
much
below
that
unless
it's
unusual,
Otis
they've
been
up
here
with
six
degrees,
which
was
a
lot
of
fun.
Seeing
as
how
he's
running
the
Canon
totally
manually,
including
the
exposures.
A

Work
wonders
on
the
gas
prices
yeah
little
different
up
here
than
in
San
Jose
nobody's
building
this
terribly
serious
in
Tuolumne
County,
because
there's
only
been
two
confirmed
cases:
a
co
bid
period
in
the
entire
time
of
the
epidemic
and
they
all
got
and
they
came
from
a
cruise
ship.
So
go
figure.
I.
