Now
the
polar
alignment
in
nina
so
far
was
very,
very
primitive.
It
was
just
slightly
more
refined
than
the
drift
alignment
now
they
have
a
new
three
point:
polar
alignment
based
on
plate
solving,
so
the
it
takes
three
pictures
of
the
sky
spaced
by.
I
believe
the
default
is
20
degrees,
but
you
can
you
can
set
whatever
you
want.
D
Those
don't
need
to
be
in
a
around
the
pole.
So,
even
if
you
have
a
obstructed
view
of
up
north,
you
can
still
align
your
telescope,
so
it
takes
the
three
pictures.
Plate
solves
calculates
the
deviation
from
where
your
polar
polar
axis
is
pointing
and
where
it
should
be,
pointing
and
guides
you
through
the
process
of
realigning
changing
the
azimuth
and
the
altitude
of
your
polar
axis.
D
In
theory,
it
should
take
you
there
with
just
one
one
run,
but
I
noticed
that
there
are
some.
I
don't
know
if
there
are
round
off
errors
or
just
the
first
degree
approximation
ever
it's
more
precise.
If
you
run
it
twice
and
it
gets
you
easily
within
less
than
one
one
minutes,
one
minute
of
arc
for
sure
I
did
20
seconds
and
it's
it's
pretty
good.
It's
convenient.
If
you
don't
have
a
view
of
the
pole.
D
A
D
Cap
can
even
correct
for
atmospheric
refraction,
which
I
mean
for
at
our
latitude,
is
about
one
arc
minute.
So
it's
not
that
much
but
yeah
you
can
do
it.
If
you
want,
then
it's
a
debatable
whether
it's
best
to
align
with
the
refracted
pole
or
with
the
true
pole,
but
shopkap
offers
that
option,
whereas
nina
doesn't
offer
that
yet
you
get
the
refracted
pole
and
that's
it.
D
D
D
D
I
wanted
to
understand
if
what
kind
of
advantage
would
be
there
in
using
a
mono
camera
compared
to
the
dslr,
and
I
was
blown
away
and
the
jaggernut
who
provided
the
some
sample
dart
frames
that
I
needed
to
see,
because
if
you
look
online,
there's
lots
of
people
that
complain
about
the
amp
glow
of
this
camera
and
it
as
in
general,
it's
true
for
any
type
of
sophisticated
equipment.
There's
a
lot
of
people
who
complain,
there's
a
few
people
that
are
happy
and
post,
so
you'll
find
lots
of
bad
reviews
it.
D
D
I
the
I
take
a
so
far.
I've
taken
one
library
of
darks
compared
with
the
dslr
where
you
you
cannot
really
do
it
because
the
you
have
no
control
over
the
temperature,
the
the
cooled
camera
and
the
temperature
stabilized
camera
is
incredibly
easier
to
use
in
that
in
that
regard,
and
you
don't
need
to
do
any
form
of
dark,
dark
scaling
or
optimization
unless
you
want
to.
Of
course,
I
found
that
the
files
are
much
easier
to
process
than
than
beard
profiles
from
a
dslr.
D
D
D
I
I
wasn't
prepared
for
the
fact
that
the
the
single
most
evident
advantage
of
the
mono
camera
compared
to
the
dslr
is
in
the
sharpness.
I
was
expecting
noise
pro
and
advantage
or
benefits
in
saturation
of
color.
Yes
they're,
both
there
but
the
sharpness.
It
really
kicks
the
ball
out
of
the
field.
It's
incredible!
D
So
when
you
say
sharpness,
you
mean,
apart
from
focus
entirely
just
the
empty
wow.
I
think
it's
because
the
the
the
filters,
the
filters
that
I
got
have
a
very
almost
a
rectangular
transmission
window
so
enjoy
yeah.
Each
of
the
three
color
is
focused
exactly
in
that
color
and
nothing
else.
Even
though
I
have
an
upper
chromatic,
refractor,
there's
always
some
level
of
focus
shift
between
the
red
and
blue
yeah.
I
was,
I
was
impressed
right
now.
I'm
taking
I've
been
taking
so
far
10
hours
from
from
my
backyard
on
m13.
D
Right
yeah,
I
I
have
no
user
for
a
47,
megapixel
camera,
sorry
yeah,
so
this
is
a
m13
and
that
I
I'm
currently
processing
it's
10
hours
of
information
from
the
balcony
so
from
the
backyard.
So
it's
about
three
hours
and
a
half
for
each
of
the
three
rgb
colors
in
the
course
of
four
nights,
and
let
me
let
me
zoom
in
and
I'll
show
you
what
I
mean
by
sharp.
It's
really
the
stars
are
pinpoints.
I'm
impressed.
D
You
can
see
some
distant
galaxy
clusters
like
this
one
or
slightly
closer
galaxies
like
this.
I'm
gonna
add
more
data,
of
course,
and
it's
this
is
from
the
bottom
seven.
So
this
there's
no
there's
the
noise
in
the
background
from
pinnacles.
It
was
much
better.
I
don't
know
if
you
let
me
stop
this
showing
and
share
another.
D
This
is
the
firework
galaxy
that
I
imaged
from
pinnacles
10
days
ago.
As
I
said,
it's
not
very.
It's
not
super
sharp.
The
the
stars
are
a
little
bit
bloated
because
of
the
poor,
seeing
but
the
yeah
there's
there's
detail.
The
noise
is
very
well
contained.
The
colors
are
nice.
You
can
see
the
h2
regions
and
the
the
camera,
although
this
in
the
galaxy,
although
this
is
just
an
rgb
integration,
I
had,
and
I
don't
have
a
narrow
band
filters
yet
so
I
couldn't
add,
h
alpha
to
make
things
easier.
A
B
D
D
So
inside
that
folder
you
find
the
subfolder
called
flats,
one
called
darks,
one
called
lights
and
the
within
this
new
tool.
You
can
open
the
the
root
folder
in
the
parent,
folder,
not
the
root,
and
it
would
on
his
own
understand,
which
ones
are
light,
which
ones
are
dark
and
dark
flats
based
on
the
the
metadata
and
put
them
in
the
in
the
correct
tab.
That's.
D
And
if
you
don't,
if
it
doesn't
get
it
right,
you
can
always
change
it
manually
without
having
to
import
anything.
You
just
go
into
the
cont
in
the
control
panel.
I
think
it's
called
the
tab
and
you
choose
the
the
set
of
lights
that
you
want
to
calibrate
and
there's
a
pop-up
menu.
You
can
choose
what
what
flats
will
be
used
for
that.
D
G
D
D
G
G
D
F
D
A
D
D
The
whatever
whatever
length
of
exposure
is
needed
for
each
of
the
filters
will
be
repeated
with
the
dark
field,
with
the
either
the
dark
filter
when
you
put
the
cap
on
the
telescope,
but
I
think
that,
given
this
camera
has
so
little
thermal
signal,
if
anybody
is
interested,
I
did.
I
already
did
some
analysis
of
the.
How
much
is
the
thermal
signal
and
it
actually
matches
what
zwo
says?
D
Interestingly,
but
so
the
thermal
signal
is
so
little
that
I
think
that
you
could
get
away
with
an
elaborate
of
a
flat
darks
exposed
for
one
or
two
seconds.
My
typical
exposure
is
between
two
and
three
seconds
and
there
wouldn't
be
essentially
any
change
with
narrowband,
where
you
have
to
expose
it
for
maybe
30
seconds
for
a
flat.
It
could
be
different
for
rgb.
I
don't.
I
don't
see
it
as
critical.
D
With
a
slightly
different
length,
because
there
is
a
it
removes
the
offset
as
well,
if
you
don't
do
it,
given
that
we
don't
calibrate,
even
the
cmos
are
not
really
suitable
for
calibration
with
the
with
bias
you
still
have
all
the
offset
so
just
and
with
the
with
mo
with
other.
This
is
common
with
other
zwo
cameras,
the
linearity
somehow
changes
between
one
zero
seconds
and
one
second,
so
anything
exposed
for
less
than
one
second
has
a
different
response
than
anything
exposed
more
than
one
second.
D
E
F
D
The
read
noise
is
a
1.974
electrons,
so
very,
very,
very,
very
low.
A
strange
characteristic,
the
read
noise
in
this
camera-
he
is,
it
shows
up
as
banding.
So
if
you
look
at
the
at
the
dark
frame,
we're
gonna
see
that
our
horizontal
bands
change
from
from
frame
to
frame.
So
it's
actually
noise,
but
it's
a
has
a
structure
which
is
strange.
D
D
I
I
don't
have
a
clue
why
it's
not
related
to
the
way
that
it
is
illuminated.
Even
if
I
I
get
very
strange
patterns
in
the
in
the
flats,
even
if
I
rotate
the
the
ipad
compared
relative
to
the
telescope.
There's
no
change
in
the
pattern
and
the
no
amount
of
diffusing
material
that
I
can
put
in
between.
I
actually
went
and
I
bought
a
quarter
inch
thick
nylon
cutting
board
to
act
as
a
diffuser.
D
So
there's
no
pattern
can
go
past
that,
but
still
it
shows,
then
I
I
realized
that
if
I
take
sky
flats,
there's
no
pattern
at
all,
so
it's
not
a
problem
with
the
camera
or
with
the
filter
and
the.
To
my
surprise,
I
I
took
out
from
cold
storage
and
an
old
ipad
2
that
I
that
I
had
and
the
ipad
2
makes
the
most
beautiful
flats
the
ipad
pro.
Does
the
294
doesn't
like
it,
but
it's
fine
with
the
ipod
too.
So
I
don't
have
a
good
explanation.
D
A
D
H
F
F
F
F
A
F
F
There
was,
I
also
got
the
focuser
at
the
same
time
as
as
the
camera.
That
was
a
fluke,
as
you
know
that
we
went
through
a
long
period
there,
where
none
of
the
dealers
had
anything
on
the
shelves.
So
if
you
saw
it,
you
you'd
better,
get
it
right,
then
or
it'll
be
gone.
That
happened
with
the
camera
and
with
the
focuser
I
got
it.
F
F
F
F
Many
of
the
things,
of
course
that
I
learned
using
this
star
adventure
and
the
nikon
camera
do
carry
over
I'm
still
using
apt,
astro
astrophotography
tool
to
run
the
rig,
but
I
discovered
it
has
three
times
more
features
than
I'd
ever
been
using
as
they
just
I
didn't
have
the
equipment
to
use
those
features.
So
I
had
to
learn
a
whole
lot
of
new
features.
F
F
F
F
F
F
F
F
Well,
this
this
vw,
oh
eaf,
focuser,
is
absolutely
great
for
this,
william
optics
61
mod
mark
ii.
That
was
a
piece
of
cake.
Well,
when
I
got
the
mount
I
discovered,
there's
oh
there's
something
else
you
have
to
provide
for
which
just
happened
to
work
out
with
my
old
rig.
It
doesn't
work
with
this
rig.
F
F
F
F
And
here
you
can
see
that
the
we
have
just
enough
space
for
the
focuser.
I
decided
I
better
learn
these
things
in
I'm
learning
apt
learning
how
to
use
a
cooled.
Camera
learning
how
to
use
a
focuser,
including
autofocus,
with
apt,
which
is
a
they
have
a
a
whole
new,
improved
autofocus
or
an
apt,
and
it
really
works
great,
except
it
is
slow
it.
It
takes
six
minutes
to
do
an
autofocus.
F
You
just
tell
it
how
many
focuser
steps
per
degree
you
want
it
changed
and
it
will
track
it
through
the
night
and
I've
only
done
this
once
this
whole
thing
is
so
new
to
me.
I
I
just
finally
set
it
up
to
make
the
automatic
adjustment
and,
at
the
end
of
the
evening
I
did
another
autofocus
to
see
how
close
we
were,
and
I
the
difference
was
in
the
noise
level.
F
It
was
like
three
or
four
focuser
steps,
which
is
the
kind
of
thing
that's
smaller
than
the
repeatability
error,
so
that
worked
out
fine,
but
I
had,
I
didn't,
have
a
huge
change
either,
but
apparently
I
I
did
pick
a
good
coefficient,
so
I
said
I'm
not
going
to
go
to
a
dark
site
and
with
a
long
drive,
while
I'm
learning
how
to
use
this,
I
do
it
from
the
patio
I
took
this
picture
last
night
of
the
our
side.
Patio
and
I've
worked
out
there.
F
There
is
a
street
light
on
an
eight
foot,
high
pole
and
this
I
just
discovered
this
problem
in
the
last
in
the
last
month,
sometime
about
six
months
ago,
that
light
burned
out-
and
I
said,
lori
under
no
circumstances
are
you
to
call
and
report
that
that
needs
to
be
fixed,
but
apparently
somebody
did
call,
and
so
about
a
month
ago
they
fixed
it
and
the
lights
back
on,
and
this
picture
was
taken
right
after
sunset.
The
light
had
just
come
on.
F
This
picture
was
taken
about
45
minutes
later,
and
you
can
see
that
light
is
lighting
me
up
thoroughly.
There's
another
one.
Just
like
that
light
is
about
40
feet
away,
there's
another
one
behind
me
as
I'm.
Taking
this
picture
also
about
40
feet
away.
It's
you
can
see
the
the
top
of
the
fence
is
lit
up.
There's
another
one
across
the
street:
this
is
this
is
totally
not
a
good
place
to
take
fine
astrophotos,
but
it's
what
was
available.
G
Glenn
will
show
you,
though,
that
you
can
fix
that
with
a
little
cardboard.
I
mean
plywood
now
right,
glenn,
all
right.
If
he
doesn't
say
it
I'll
say
it
yeah.
So
what
you
do
is
you
put
you
you
just
screw
some
ply.
You
know
plywood
two
feet
above
your
fence
in
the
direction
of
those
lights,
and
I
you
know
it's
not
going
to
be
pinnacles
but
it'll
be
better.
F
F
You
know
about
eight
or
nine
feet
high
and
just
temporary
each
night,
but
the
secret,
though
in
taking
pictures
in
this
kind
of
environment,
is
just
to
keep
at
it.
If
you
I
started
out
at
the
end
of
may,
I
wanted
to
learn
how
to
use
the
apt's
automatic
meridian
flip,
so
somebody
had
just
mentioned
to
me
m101
and
the
fact
that
it
never
sets
for
those
of
us
at
this
latitude.
A
I
I
I've
done
a
little
bit
of
photometry
like
like
I've,
taken
other
people's
images
and
run
numbers
on
that
and
stuff
with
my
grad
school
research
and
stuff.
But
I
am
you
know,
I'm
often
like
teaching,
students
and
stuff
like
that,
and
I'm
often
in
some
sort
of
position
where
we're
interested
in
doing
some
sort
of
like
night
out
and,
like
you
know
they
they
want
to
do
some
sort
of
camping
under
the
stars
kind
of
thing,
but
I
also
am
interested
in
getting
into
astrophotography.
I
So
this
is
that
the
first
time
I'm
ever
hearing
of
pinnacles,
I'm
actually
not
from
california.
So
I
was
just
wondering
I
guess
as
a
more
direct
question.
If
there
is
interest
in
like
if
people
go
out
to
pinnacles,
is
this
the
type
of
place
I
was
just
looking
it
up?
Is
this
the
type
of
place
that,
like
I
know,
certain
meetup
groups
that
I'm
sure
would
like
to
go
out
there
as
a
group
or
something
like
that.
B
I
A
A
That
distinction
as
the
newest
national
park
and
it's
a
beautiful
place
and
I'm
sure
that
there
are
meet
up.
You
know
things
going
on
over
there
during
the
day
and
we
have
had
meetups
and
you
know
club
functions
in
the
past
that
were
observing
versus,
observing
and
also
astrophotography
get-togethers.
B
A
Been
limited
lately
by
covid
situation
for
as
far
as
getting
together
in
groups,
but
my
associate
here,
glenn
newell
runs
workshops
not
in
tentacles
but
in
other
places
that
we're
hoping
to
get
things
going
on
soon.
We've
we've
got
these
starry
nights,
star
parties
that
happen
in
the
area
and
a
couple
different
places
that
people
are
going
to
observe
and
you
know
so
there
are.
There
are
ways
that
you
can
get
out
and
get
under
the
stars
and
observe
or
watch.
E
E
K
E
E
These
are
all
ones
that
that
well,
I
guess
I
haven't
been
to
all
these
places,
but
anyway,
there
are
other
sites
that
that
we
have,
in
cooperation
with
the
open
space
authority,
the
santa
clara
open
space
authority
and
those
are
places
that
we
go
to
have
events
with
osa,
docents
and
there's
there's
we
do
imaging
workshops
or
clinics
at
a
place.
That's
only
like
half
an
hour
from
san
jose
and
it's
you
know
not
anywhere
near
as
dark
as
pinnacles,
but
it's
it's
pretty
dark.
It's.
E
L
L
L
D
A
D
I
Very
good
well
go
ahead,
I
was
gonna
say
for
my
purposes.
I
think
what
glenn
showed
me
at
first
was
great.
You
know
these
alternate
viewing
locations
and
then
some
of
the
events
he
was
talking
about.
I
definitely
like,
as
time
goes
on,
I
I
would
definitely
be
interested
in
in
attending
and
checking
those
out,
yeah
yeah
and
then
some
of
these
other
locations
are
great
too.
I
I
definitely
want
to
look
into
this
and
I
also
was
wondering
about
purchasing
my
own
starting
equipment.
I
E
E
You
know
three
or
four
telescopes,
while
you're
figuring
it
out
right.
You,
you
first
of
all
figure
out
if
you're
really
interested
or
not
right,
and
then
what
equipment
you
like
to
work
with
before
you
go
and
and
spend
money.
The
other
thing
is
you
know
if
you
come
to
some
of
my
events,
you'll
see
what
people
have
purchased
and
what
works
for
them.
E
Also,
a
great
resource
which
I
I
talk
about
and
my
my
lectures
are-
are
online
by
the
way
on
the
sja
youtube
channel
and
my
channel
is
astrobin,
so
most
of
us
post,
our
our
stuff
on
a
site
called
astrobin.com
and
one
of
the
things
that
people
do
when
they
post
there
is
they
post
the
gear
that
they
use
to
take
the
image.
So
if
you
were
interested
in
you
know
a
certain
camera
like
francesco
was
talking
about.
D
Excellent
about
pinnacles
until
the
year
2019
before
kovid,
the
sja
and
the
the
parked
rangers
co-hosted,
the
star
parties,
public
star
parties
there
and
the
problem
with
pinnacles
on
the.
When
you
do
something
on
the
on
the
weekend.
On
the
east
side,
you
have
to
hope
that
people
don't
see
you
not
because
it's
illegal,
but
because,
if
they
see
you
you're
going
to
have
200
people
that
want
to
look
through
your
telescope.
A
F
A
A
A
F
A
F
This
is
a
tiny,
tiny
piece
of
the
full
frame
that
was
actually
one
of
the
things
I
thought
was
good
about
getting
the
25
megapixel
sensor
is,
I
could
take
a
fairly
small
piece.
This
is
like
1300
pixels
wide
by
800
pixels
high,
so
the
stars
are
a
little
bit
big,
but
the
nice
thing
about
having
the
new
mount
you
see,
the
stars
are
pretty
round
and
that's
what
you
get
with
five
hours
on
a
well-lit
patio.
F
F
F
G
Before
before
young,
can
I
just
cut
in
for
a
second
since
we're
an
hour
in
the
meeting,
and
you
know
after
a
little
while
sometimes
people
tend
to
cut
off.
I
just
wanted
to
point
out
to
you,
folks
that
this
is
bruce's
last
meeting
as
as
host
and
I'll
be
taking
over
and
bruce
has
done
an
amazing
job
for
four
years
or
so,
and
I
really
think
he
needs
a
little
round
of
applause.
So
could
you
please
unmute
yourself
and
clap
or
stuff
like
that.
G
C
I
appreciate
it.
May
I
cut
in
with
a
question
sure
I'm
also
a
new
guy,
my
name's
rich.
I
do
have
a
telescope
in
camera
and
have
started
photography,
but
I
believe,
as
bruce
had
mentioned,
we're
about
to
start
new
moon
saturday
night
observing
sessions
again
july.
10Th
is
a
new
moon
and
it
happens
to
be
a
saturday.
Should
we
expect
one
then.
E
So
probably
what
that
will
be
is
what
I
would
call
a
field
clinic
versus
a
public
workshop.
So
it
would
be
sjaa
members,
and
my
hope
is
that
at
least
some
of
the
people
that
are
that
are
further
along
in
the
hobby
would
would
be
helping
me
test
out
some
some
screen
sharing
with
local,
wi-fi
and
whatnot,
so
that
when
we
have
the
public
there,
we
can
show
them
things
from
our
telescopes
on
their
smart
devices
and
they
won't
have
to
lean
right
over
us.
E
You
know,
masks
or
no
masks
because
of
the
the
continuing
risk
of
covid
or
or
what
have
you.
So
that's
what
I'm
hoping
for
the
next
session-
and
I
can
talk
more
about
that
and
the
the
clinics
will
not
be
when
we
do
these
sja
private
events,
they're
they're,
not
on
meetup
they're,
on
the
sjaa
astro
dash
astro
imaging
google
group.
So
if
you're
not
already
on
there,
then
you
wanna
you
wanna,
get
on
that
yeah!
I
just.
A
E
Yeah
perfect,
so
the
you
know
the
the
the
clinics
I
generally
might
not
even
take
a
rig
myself,
and
the
idea
is
that
myself
and
others
would
be
more
available
to
help
people
kind
of
hands-on
with
their
rigs.
And
it's
more.
You
know
for
the
club
members
to
to
get
together
and
get
some
photons
and
then
the
public
workshops.
E
So
that's
the
difference
between
what
I
call
the
the
astro
imaging
workshops
and
the
field
clinics.
That's
how
it's
been
in
the
past
and
I'm
I'm
looking
to
try
to
shake
things
up
a
little
bit
and
do
some
different
things
going
forward.
But
most
of
my
energy
has
been
going
into
helping
the
the
visual
side
learn
some
astrophotography
for
the
public
outreach
public
star
parties
again
so
that
they
can
share
views
through
their
telescopes
to
people's
smart
devices.
E
So
people
don't
have
to
come
up
and
put
their
eyes
and
hands
on
the
on
the
telescope
right
and
it's
not
only
to
protect
the
observer,
but
also
that
you
know
we're
not
spreading
germs
between
the
various
attendees
and
and
stuff
too,
which
could
be
a
liability
for
the
for
the
club.
So
that's
where
that's,
where
I've
been
spending
a
lot
of
time
with
with
the
technology
and
and
seeing
what
the
visual
observers
can
can
easily
absorb
versus
doing
full-on
astrophotography.
E
E
A
K
Okay,
yeah
last
week,
grant
sent
out
the
email
regarding
the
latest
piece
of
insight
include
a
new
normalized
scale,
gradient
tool.
You
know
script
so
and
lastly,
I
I
did
make
a
try.
I
tried
out
and
it
ended
up
pretty
good
so
and
for
I'd
like
to
show
you
it's
a
usually
right.
I
had
a
lot
of
problems
on
o3,
and
so
it
always
has
a
lot
of
sky
gradient
so
and,
and
I'm
going
to
show
you
those
frames,
okay,
they
are
without
normal
light
scale
gradient.
K
So,
okay,
let
me
stop
so
you
can
see
the
curl
and
gradient
show
up
sometimes
late
and
dry
late
and
dry.
So
and
then
I
I
apply
this
one.
We
with
the
same
frame
right.
I
apply
with
a
normalized
scale
gradient
so
and
in
general
right.
The
gradients
reduce
a
lot
and
especially
after
the
integration
it
look,
it
look
much
better.
So
I'm
I'm
going
to
show
you
the
result
and-
and
this
one
is
for
script,
yeah
speak
level
is
very
fake
neighbor.
J
K
K
K
K
K
G
G
K
Okay,
yeah
extra
time
cnn
so
and
then
you
know
you
usually
just
adjust.
This
number
try
to
make
those
a
point
in
line
with
this
reference,
but
you
know
for
me
right.
I
just
I
just
take.
I
just
take
a
default
value
and
so
very
simple.
You
just
choose
your
fifth
frame
as
a
reference
and
click:
okay,
that's
it
and
then
oh
and
then
it
will
create
a
white
key
and
wait.
K
G
K
K
K
K
And
and
this
this
user
normally
creating
a
scale
rating,
it
got
better
contracts
and
also
you
know
you
see
here
so
bad
right,
much
better.
I
sky
here
this
side
and
this
this
time
here
is
a
little
bit
better,
and
so
that's.
I
think
that
is
a
very
good
script
to
to
renting
the
sub
frame
yeah.
So
it's
good
one
yeah.
G
A
K
K
G
K
K
A
A
B
So
this
is
the
lagoon
nebulae,
m8
and
21-2,
but
whatever
so.
This
is
down
in
the
sagittarius
or
it's
in
scorpio.
Anyway,
it's
down
there.
You
can
practically
see
it
with
the
naked
eye
and
when
the
conditions
are
good.
At
least
I
used
to
be
able
to
before
my
like
getting
old,
but
I'm
taking
this
picture
with
an
11
inch
vasa,
which
is
a
very
fast.
B
B
B
B
E
I
haven't
made
time
to
do
it
yet,
but
I've
been
amazed
again
with
the
the
auto
integrate.js
script
that
uses
cosmetic
correction
to
to
do
things
that
I
always
struggled
with
when
I
was
using
it
manually
to
remove
column
defects.
And
so
I
keep
meaning
to
open
up
the
javascript
and
see
what
it's,
what
it's
doing
but
well.
B
B
E
Good
or
bad
yeah
well,
one
of
the
the
challenges
with
the
the
raza
you
know
is
having
that
many
subs
right
and
there's
a
lot
of
programs
that
choke
on
that
amount
of
data
they
run
out
of
memory
or
whatnot.
I
know
that
before
I
was
using
pix
insight,
ccd
stack
would
would
do
that
and
like
the
weighted
batch,
p,
pre-processing
script
and
pix
insight
tends
to
run
out
of
memory
due
to
java
script.
Garbage
collection
problems.
E
I
guess,
but
I
was
pleased
I
again
singing
the
praises
of
the
the
auto
integrate
script.
I
did
go
back
and
found
some
data
that
I
had
never
successfully
processed
because
it
was
from
a
rasa
11
in
color
asi
1600
from
itilloscope.net
for
a
while.
They
had
that
that
combination
available-
and
I
had
let
me
see
what
was
it
here-
200
some
odd
205
60.
Second
exposures-
that
I
was
never
able
to
successfully
process
before
and
with
the
auto
integrate
script.
H
Glenn
yeah
all
right
talking
about
how
to
integrate.
In
my
experience
I
had
to
I
tried,
but
I
have
to
stop
with
the
previous
version,
not
the
very
last
one
of
exercise,
because
I
was
having
a
lot
of
crashes
on
my
on
my
installation
of
pixie
side.
I
have
no
idea
why
they
were
classical
referred
to
zero
memory,
something
like
that.
H
I
let's
say
take
away
that
I
reinstall
it
pics
inside
and
magically
they
disappear
now
they
haven't.
I
have
installed
the
new
version
of
pixel
inside
the
last
one.
The
last
week
and
honestly,
I
have
not
yet
tried
the
doubt
integration
script
again.
I
will
soon,
but
that
was
my
experience.
Without
the
degree
it
was
strange.
E
E
Maybe
four
versions
since,
since
we
last
talked
last
month
so
be
sure
you
get
the
latest
like
I
used
to
it,
used
to
bomb
out
on
one
shot
color,
and
this
was,
as
I
said,
a
color
asi
1600
in
the
rasa
11
and
it
processed
all
the
way
through
without
a
problem.
But
so
I
don't
know
what
to
tell
you
other
than.
E
H
B
Well,
it
seems
like
I
seem
to
have
avoided
a
lot
of
a
lot
of
issues.
One
thing
I
never
use
batch
processing.
I
do
it
step
by
step,
because
I
I'm
going
to
do
a
several
step
culling
of
my
subs.
I
mean
I'm
going
to
use
blink
sure
I
am,
but
also
I'm
going
to
use
a
subframe
selector
and
use
that
to
select
it.
B
How
I
I
seem
to
have
avoided
some
of
those
issues.
I
also
don't
use.
Well,
I
guess
it's
subframe
selector
for
the
subtitle,
I'm
getting
some
sort
of
weighted
average,
but
I
don't
do
normalization
either
because
of
where
I
am.
I
don't
really
need
to
do
that,
because
I'm
always
hovering
around
portal
two
and
a
half
three
stars
as
far
as
the
scene
goes
up
here,
with
the
transparency
and
whatnot.
B
B
G
G
Okay,
good,
so
I've
lost
you
guys,
but
I'll
talk.
So
this
is
my.
This
is
a
transition
photo
for
me.
I've
used
the
refractor.
You
know
560
millimeter
refractor
exclusively
until
about
a
month
or
two
ago,
when
glenn
lent
me
a
8-inch
rc,
and
so
this
is
the
only
picture,
but
I'm
happy
with
it.
The
first
picture
and
only
picture
I've
taken
with
you
know
something
with
a
longer
focal
lens.
So
this
is
a
1600,
millimeter
or
so
focal
length.
It
has
this
odd
thing.
G
G
A
A
G
Okay,
we'll
just
stick
with
lightroom,
it's
funny,
because
it's
sort
of
odd
on
my
screen,
but
I
don't
care
okay.
So
there
you
go
so
it's
the
needle
and
yeah.
I
mean
you
know
my
first
shot
and
things
took
a
while
to
understand
why
the
long
focal
length
was
different
and
all
the
mistakes
you
know
like.
I
went
back
a
few
years
and
started
making
the
kind
of
mistakes
I
made.
G
You
know
in
the
beginning.
That's
one
of
the
things
I
wanted
to
mention
to.
I
forget
your
name,
the
guy
who
was
talking
about
bringing
kids
and
who
did
as
astrometry
is
he's
still
there
yeah
yeah
yeah.
It's
I'll
tell
you
my
advice.
Is
it's
it's
a
difficult
hobby,
it's
well
worth
pursuing
and
sticking
with,
but
it
isn't
the
simplest
thing
to
get
going
in
the
beginning.
G
So
you
know
expect
a
few
bumps
on
the
road
in
the
beginning.
That
was
my
experience
in
the
beginning
and
then
I
had
a
lot
of
smooth
sailing.
Then
I
borrowed
this
telescope
and
you
know
it
took
me
a
few
weeks
till
I
got
back
to
where
I
was
so
that
a
few
weeks
instead
of
a
few
you
know
six
months
like
in
the
beginning.
I
can't
complain.
I
made
mistakes.
Like
you
know
my
my
plate.
Solving
wasn't
working
well
duh,
I
didn't
have
any
of
the
small.
G
You
know
sized
solver
files
loaded
because
with
my
refractor
you
know
with
a
one
and
a
half
degree
field
of
view,
you
don't
need
things
that
are
20
arc
minutes
and
all
of
a
sudden.
Now
I
did
anyway
there
you
have
it
so
needle
galaxy,
oh
by
the
way.
Another
funny
thing
and
just
an
anecdote
of
this
story
is
you
know
it's
sort
of
nice
that
you
get
that
those
dust
lanes
in
the
needle
right.
G
I
mean
this,
isn't
you
know
picture
of
the
day
or
anything,
but
I
was
happy
with
it.
But
the
funny
thing
is:
is
the
subs?
You
know
they
just
look
like
you
know
like
a
white
two
white
things
with
dark
in
between,
and
you
don't
see
that
dust
at
all
on
the
subs
to
really
have
to
integrate.
Before
you
see
something
like
that
which
was
comical
to
me
and
I
look
at
these
subs
and
I
go
that's
weird-
I'm
doing
something
wrong,
but
it
integrated
just
fine.
A
A
G
A
M
Hey
bruce,
this
is
marcel.
I
have
a
question
hey.
I
joined
several
of
these
meetings.
I
really
learned
a
lot
and
I
I
love
listening
to
you
guys
and
see
that
you
have
very
similar
problems
to
what
I
have
so
I
was
working
on
a
project.
I
recently
also
got
into
3d
printing,
and
so
I
I
noticed
that
you
generally
don't
find
button
of
masks
for
like
really
small
focal
lengths
and
I
see
glenn.
M
M
M
You
know
angle
that
you
go
for,
and
but
nobody
tells
you
really
what
the
distance
between
the
spikes
should
be
between
the
these
things
should
be,
and
the
online
generators
for
these
normally
break
for
short
focal
lengths.
They
don't
really
work
very
well,
so
just
wanted
to
check
if
anyone
has
done
something
with
it
before.
E
E
Yeah,
so
that's
for
so
for
what
I
did
was
I
figured
out
what
my
biggest
dslr
lens
diameter
was
physical
diameter.
Not
the
you
know,
so
it
was
like
72.
I
think
so.
I
bought
a
an
85
millimeter
one
of
these
and
a
filter
holder,
and
then
I
just
use
that
same
one
on
all
the
different
camera
lenses
that
I
have
real
quick.
I.
G
M
M
B
F
B
B
If
you
do
want
to
go
to
a
fairly
advised
star
to
focus,
I
have
a
commercial
bass
and
off
match
that
I
got
for
my
11
inch
and
it
works
okay,
but
if
it
had
three
times
the
number
of
slots
it
would
be
able
to
work
much
better
on
a
star,
so
wouldn't
that
wouldn't
be
necessary
to
have
to
go
hunting
for
fighter
star.
So
that's
sort
of
my
experience.
I
cut
my
baton
off
mask
out
of
the
for
sale,
sign
from
the
hardware
store
with
an
exacto
knife.
B
D
B
H
A
H
H
M
H
E
F
M
A
H
F
M
To
say
thank
you.
This
is
very
helpful,
so
I
will
try
to
get
it
as
narrow,
as
this
printer
can
do
and
see.
If
that
that
helps
and
francesco
what
you
showed,
the
the
transparent
one.
I
already
you
know,
I
love
the
william
optics
build-in
betting
of
mask
and
they
are
also
transparent.
So
I
think
that's
also
part
of
the.
M
E
B
E
E
F
Off
mask
yes,
this
is
this
is
85
millimeter,
and
what
I've
done
here
is
I've
put
little
felt
pads
on
it,
and
this
just
fits
over
the
I
just
put
it
on
the
I'm,
not
g
good.
At
using
this
camera.
I
can
see
that
anyway,
little
felt
pads
to
keep
it
from
falling
off
of
the
lens
hood
yeah.
That
is,
and
that
is
so
quick
compare.
I
I
didn't.
I
didn't
buy
the
filter
holder
because
I
said
well.
E
Well,
the
the
filter
holder
has
a
set
screws
to
where
you
can
take
off
just
a
part
of
it.
So
the
the
bulk
of
the
filter
holder
stays
on
the
lens,
while
you're
doing
your
astrophotography
and
you
just
sort
of
put
in
the
you
know
put
in
the
filter
with
one
with
one
screw
so
that
you
don't
mess
up
your
focus
after
you
after
you've
achieved
it.
But
yeah
I
mean
that's
a
that's
a
great
solution,
the
the
filter
holder.
E
F
Well,
it's
a
wonderful
about
enough
mask
and
the
nice
thing
if
you
go
to
his
website,
he's
got
a
table
there.
That
will
tell
you
for
each
focal
length
for
each
f
number.
Is
this
going
to
work
for
you
or
is
it
not,
and
he
really
has
a
good
numerical
prediction
as
to
whether
it
works
and
it
works
very,
very
well.
E
E
H
Or
discuss
yeah,
just
one
last
thing
for
marcel
also,
I
will
sorry
I
can.
I
cannot
be
more
precise
right
now,
because
I
am
on
the
phone
and
not
at
my
pc,
but
there
are
also
very
interesting
little
program,
free
online
batting
of
the
screen
grabbing
and
that
that
will
help
you
to
focus
because
you
can
enter
in
those
program.
H
A
E
You
know
out
in
the
in
the
wild
with
no
prerequisites
right,
so
they
just
show
up
with
their
devices
and
aim
their
phone
at
a
qr
code
to
join
a
local
wi-fi
that
we
set
up
and
then
each
station
you
know
what
what
would
have
been
each
telescope
down
the
road.
A
star
party
would
have
their
own
little
qr
code
that
you
could
point
your
phone
at
to
to
see
what
they're
doing
on
their
on
their
telescope
so
had
some
pretty
good
learnings
and
the
the
price
went
way
up.
E
So
I
started
with
you
know
little
third
inch
sensor,
one
shot
color
cameras,
and
that
proved
to
be
too
challenging
to
get
on
the
sensor
going
from
an
eyepiece
to
to
the
camera
for
the
visual
observers
without
without
doing
any
plate
solving
or
anything
so
we're
looking
at
the
I'm
gonna
mess
up
the
name
now
francesco.
What
was
your
camera
again?
E
E
So
that's
a
700
camera
instead
of
you
know
three
four
hundred
dollars
and
then
also,
I
think,
a
quality
flip
mirror
with
a
lighted.
Reticle
eyepiece
will
be
required
as
well.
So,
but
you
know
it's
been
so,
we've
been
out
in
the
field
twice
and
it's
been
a
real
learning.
Experience
like
I
was
all
hot
on
these
qr
codes
and
I
figured
out
how
to
mount
them
on
a
mic
stand
with
a
guitar
pick
holder
and
all
this
stuff,
and
then
somebody
said
well.
E
What
are
you
gonna
do
because
it's
night
and
people-
and
I
hadn't
even
thought
of
the
fact
that
you
know
these
things
were
weren't
your
cameras
weren't,
going
to
be
able
to
see
it
at
night,
so
embarrassing.
But
so
now
we
have
backlit
signs
right.
So
and
now
we
have
red
backlit
signs,
and
so
it's
been
a
it's
been
a
learning
experience
so
yeah.
E
E
They
just
use
their
web
browser
so
and
just
via
qr
code
so
and
the
the
the
infrastructure
you
know
in
terms
of
the
router
and
all
that
stuff
is
is,
and
the
batteries
and
all
that
stuff
is
worked
out
too.
So
good
progress
on
all
that
yeah.
So,
basically
the
the
visual
guys.
Now
they
the
program
leads
just
need
to
go
back
and
and
decide.
