Description
This Month's Topic:
Galaxy season is upon us! This month's meeting will be an open discussion featuring some of the amazing images that our members have produced recently as well as new and ongoing project updates. Please bring your recent images & adventures to share!
A
Well,
actually,
it's
7
31,
so
I
guess
we
should
get
started.
So
I
want
to
welcome
everybody
to
the
march
16
2021
meeting
for
the
san
jose
astronomical
association,
special
interest
group
imaging
special
interest
group
tonight
we
are
going
to
have
a
general
discussion,
go
over
some
recent
images
by
some
of
our
members
and
maybe
some
projects.
People
are
working
on
and
and
we're
going
to
update
a
little
bit
on
on
the
possibility
of
getting
outdoors
together.
A
B
D
All
right,
so
this
is
the
image
that
I
captured.
Last
friday
I
decided
to
go
to
pinnacles
east.
Instead
of
the
usual
west
side,
it
was
just
a
slightly
better
forecast,
slightly
less
humid.
Most
importantly,
I
don't
like
the
drive
to
pinot
noise
west,
so
I
prefer
the
the
east
side,
despite
the
fact
that
it's
there's
a
campground
on
a
friday
night.
It
means
that
there's
lots
of
passing
cars
because
campers
arrived.
D
I
think
at
least
until
11
pm
there's
still
cars
on
our
visa
getting
in,
but
it
was
good
the
it
was
actually
the
darkest
I've
seen
in
a
while.
The
at
my
sqm
was
at
21.67
magnitudes
per
square.
Second,
I
don't
think
I've
seen
anything
like
that
recently
from
the
west
side,
which
confirms
my
impression
that
it's
actually
slightly
darker
on
the
east
side,
but
it
was
cold
and
it
went
down
to
26.,
and
so
I
I
took
two
images
during
the
night.
D
I
started
off
with
the
seagull
nebula
just
before
it
just
before
it
would
set,
but
I
was
actually
waiting
for
this
one
waiting
for
virgo
to
show
up
and
this
this
group
of
galaxies.
This
galaxy
here
is
ngc
5364.,
it's
located
in
the
in
the
eastern
part
of
the
constellation,
so
I
had
to
wait
for
it
to
to
be
visible,
but
I
really
liked
the
fact
that
it
was
a
beautiful
spiral.
D
Galaxy
not
really
face
on,
but
it
still
shows
a
structure
really
well
accompanied
by
an
elliptical
galaxy
and
some
smaller
spiral,
but
this
in
this
case
edge
on
what
I
didn't
know,
because
I
hadn't
done
my
research
unfortunately,
was
that
there
was
also
there's
also
this
cluster
here
and
I'm
zooming
in
right.
Now.
D
The
average
rail
shift
of
this
cluster
in
the
cluster
is
the
smaller
galaxy's,
not
these
larger
ellipticals,
but
the
redshift
is
a
0.08
which
corresponds
to
a
moving
distance
of
slightly
over
1
billion
light
years.
So
I
think
this
is
the
dark,
the
the
deepest
and
farthest
object
that
I
ever
imaged.
So
I'm
pretty
happy
about
that.
D
D
D
D
D
D
You
spray
compressed
air
on
it
so
that
it
gets
charged
the
electrostatically
and
then
you
you
wipe
over
the
the
sensor
phase.
The
theory
is
that
the
any
dust
that
is
there
gets
electrostatically
attracted
to
the
brush
and
you
take
it
away,
but
apparently
either
I
was
in
a
hurry.
I
didn't
do
it
right,
I
didn't
do
it
right
and
it
left
some
something
behind
and
most
importantly,
it
dislodged
whatever
was
already
on
the
sensor.
D
D
D
D
D
B
D
D
D
D
What
I
did
was
to
start
with
the
exponential
transformation,
then
some
local
histogram
equalization
to
as
you
can
see,
it
makes
the
spiral
arms
of
ngc
5364
more
prominent,
then
some
a
few
passes
of
car
or
the
enhanced
saturation
one
two
three
passes,
and
this
is
basically
it
for
this
star
net
image.
On
the
difference.
What
I
did
was
to
increase
the
saturation
of
the
stars.
D
You
can
see
it
here
more
or
less
in
the
same
amount
that
I
did
for
the
non-stellar
objects.
And
finally,
I
combine
everything
together
and
I
obtain
this
from
this
point
onwards.
It's
just
a
small
adjustments
with
the
histogram
transformation
to
put
to
bring
the
background
to
the
level
that
I
like,
I
bring
out
a
little
more
of
the
nebulosity.
D
D
D
D
Great
question,
so
normally
what
I
do
is
to
from
the
difference
image
I
create
a
mask
that
only
contains
the
the
star
cores,
so
I
bannerize
the
mask.
I
bring
it
into
photoshop
as
another
image
and
I
select.
I
use
the
the
magic
wand
once
for
selection
of
all
the
white
parts,
so
basically
all
the
cores,
I
save
the
selection,
I
reopen
it.
I
shrink
it
so
that
the
small
stars
are
left
alone.
D
D
D
D
Yeah
yeah,
I
I
I
like
this
image.
I
it's
even
this
galaxy
is
even
more
beautiful
than
I
than
I
than
I
thought,
and
the
the
unexpected
bonus
of
the
abella
1809
is
also
quite
was
was
very
nice.
Apparently,
the
image
was
a
liked
on
when
astro
bean
was
nominated
for
top
peak,
although
it
was
not
selected
for
top
pick.
D
Reading
yeah,
so
the
only
other
person
that
I'm
I'm
sure
that
it
was
a
one
of
our
members
was
nikola
nikolov
and
yeah.
The
there
were
other
another
guy.
There
were
only
all
images.
First
of
all
another
guy.
His
name
was
adam,
I'm
not
sure,
if
he's
one
of
our
members
and
he
was
imaging
with
a
an
orion
150
millimeter
refractor-
and
I
think
the
camera
was
an
asi
1600
and
then
there
was
another,
a
group
of
younger
guys.
D
We
also
imagers
with.
I
think
it
was
an
orion
80.
and
they
they
left
they
left
relatively
early.
I
don't
know
if
they
were
not
prepared
for
the
cold
caldwell
actually,
for
me,
was
a
blessing
in
disguise,
because
I
I
don't
have
any
new
heaters
for
my
telescope,
and
so
I
was
afraid
that
I
would
be
actually
forced
to
stop
early
because
of
you,
but
no
the
the
thanks
to
the
falling
temperatures.
C
D
C
D
At
the
on
the
overflow
parking
lot,
where
we
normally
have
our
star
parties,
it's
I
could
get
a
campsite
for
thursday,
but
thursday
was
the
weather
was
not
good
on
friday.
If
you,
unless
you
book
months
in
advance,
I
think
it's
impossible
and
also
friday's
very
the
campground
is
very
crowded,
so
I
think
it
would
be
mostly.
D
It
would
mostly
be
showing
the
the
universe
to
other
people
who
who
are
hanging
out
around
you,
then
imagine,
whereas
the
overflow
parking
lot.
Nobody
shows
up.
The
only
person
who
showed
up
was
the
ranger,
and
actually
he
was
so
nice.
He
was
that
he
was
concerned
that
campers
may
come
to
the
overflow
lot
and
and
disturb
us
with
their
flashlights,
and
so
he
wanted
to
know
if
he,
if
he
could
put
some
signs
on
the
road
and
not
to
that.
D
The
lot
was
closed
was
super
nice
and
it
it
wasn't
actually
a
problem
because
nobody
was,
we
didn't
see
anybody
even
trying
to
get
to
walk
to
the
to
the
overflow
lot.
It's
the
the
main
difference.
I
think
that
east
side
is
okay
for
imaging,
but
it's
not
very
appreciated
by
visual
observers,
because
for
two
reasons:
the
traffic,
both
foot
traffic
and
the
car
traffic
and
the
fact
that
there's
this,
the
the
bathrooms
nearby
heaven
their
lights,
never
go
never
go
out
at
night.
They
are
not
bright.
D
D
D
D
F
D
A
F
F
F
F
Yes,
okay,
so
first
thing
I
like
to
talk
about
color
making.
Last
year
we
we
are
discussing
about
the
nano
band,
current
mapping
and
so
every
so
I
had
a
hsa
hso
image,
ready
and-
and
then
I
I
made
it
to
here
so
it's
this
image
is
totally
broad
and
you
know
in
the
past
two
years
I
try
to
figure
out
how
to
make
a
color
correctly.
F
So
and
then
I
look
into
detail
how
to
do
that
and
so,
and
I
find
one
which
side
usually
here
right.
We
use
a
piece
of
mac,
try
to
put
a
different
mapping
equation
right,
like
a
eighty
percent,
h,
a
plus
twenty
percent
s2
to
be
a
red
channel,
and
so
we
assign
different
proportion
percentage
for
each
channel
and
sometimes
walk
by
sometimes
now
work.
So
then
I
look
into
I
found
one.
Wayside
is
pretty
helpful,
so
I
would
like
to
share
you
that
has
desktops.
F
I
like,
and
I
find
out
you
know
it's
a
it's
worked
quite
aware
for
me
because
in
the
pistol
inside
I
don't
need
to
try
the
equation.
Try
different
piece
of
mess-
and
you
know
sometimes
like
in
here
I
will
channel
10
and
I
I
still
don't
like
them
at
all
and
I
have
to
keep
trying
so
then
I
I
find
out,
I
can
use
this
one,
pretty
pretty
easy
to
adjust
the
color
to
make
the
color
where
I
like,
and
so
I'm
going
to
have
another
one
okay
before
we
start.
F
F
F
F
F
F
So
then
I
create
a
layer,
hues
and
saturation
there
and
same
thing
I
change.
I
click
colorize
and
lighten
right.
Initially,
I
will
put
minus
51
every
channel
at
the
beginning
and
then
because
it
is
a
green
channel,
so
we
put
lumber
on
the
hues
around
120
so
and
then
same
thing
creeping
this
one
to
tongues,
to
layer
so
and
same
thing
with
the
o3.
So
this
time.
F
As
a
blue
channel
same
thing,
we
put
here
so
after
that.
That's
so,
let's
see
okay,
this
all
this
one
will
be
our
initial
image,
then
so
and
then
something
not
lower.
Let
me
see-
oh
sorry,
this
one
okay.
So
this
this
image
is
look
like.
We
did
exactly.
I'm
gonna
pick
on
the
pistol
inside
very
similar.
So
we
see
the
green
is
overwhelming
with
green
color.
F
F
F
F
So
it
will
be
less
saturation
right,
so
another
way
is
lighten
lightness
is
so
I
think
we
going
too
strong.
We
we
just
move
back,
reduce
we
get
less
so
we
can
adjust
each
channel
to
where
we
like.
So
that
is
the
example.
I
I
find
is
very
flexible,
and
so,
if
you
like
get
stronger
you
should
you
will
get
a
story
which
I
think
when
I
move
here,
we
will
get
more
golden.
F
F
F
This
I
based
on
this
website
green,
gave
me
this
website,
so
I
I
find
I
thought
I
just
follow
this
one.
So,
for
example,
I'm
like
so
this
one
right.
I
imp
I
when,
when
in
the
clipping
color
greetings,
I
decided
to
keep
some
green
because
the
green
color
allow
me
to
based
on
this
mess
right.
It
will.
Let
me
generate
a
lot
of
golden
color,
so
I
like
a
more
golden
color,
so
I
keep
more
so
I
decide
to
get
more,
yellow,
sorry,
green.
F
F
Yeah
first
one
is
green,
so
we
select
the
color
and
we
I
just
follow
those
lumber
and
then
see
a
second
green
and
then
this
one
will
take
care
of
the
a
little
bit
blue
and
this
small
blue
so
and
it
will
get
the
color
I
like
and
also
during
you
know.
I
also
can
change
underline
layer.
I
know
this
is
not
good.
I
I
just
as
example,
so
we
I
still
can
fine
tune
the
color
mapping.
F
So,
and
you
know
I
got
I
so
I
think
at
this
point
I
I
like
this
color.
So
then
I
will
go
for
the
next.
The
next
one
right
is
the
high
pass.
I
think
we
talked
that
I
think
eric
presented
this
one
before,
and
I
also
in
this
page
here.
I
also
mentioned
about
high
pass
filtering
in
the
photoshop
to
to
to
increase
the
contract
and
shorten
the
image.
F
F
F
So
you
see
it
see
the
sharpening
a
little
bit
and
so
same
thing.
I
would
like
to
get
a
different.
I
I
make
a
two
copy
of
the
stylus
o3
image
and
then
I
use
the
high
pass
filter
to
to
sharpen
again
so
get
different
field
had
a
different
area.
So
so
this
is
pretty
much
near
finish,
my
stylish
image.
So
then,
here
I
I
copy,
then
I
did.
I
use
the
screen
mode
with
a
star
and
then
we
generally
start
with
a
star
image.
F
So
I
think
this
this
way
website
I
I
found
was
pretty
good
and
you
know,
and
they
helped
me
a
lot
also
they
this
seven
and
eight
two
number
seven
and
eight
had
a
lot
of
how
to
fix
the
problem
on
the
pistol
inside.
I
also
this
one
create
a
lrgb
help
too,
so
so
that's
it
so
and
second
thing
I'd
like
to
show
you
is
my
recent
m51
image.
F
Go
and
because
this
is
a
garage
image,
so
I
I
had
to,
I
cannot
do
a
status,
so
I
had
to
use
traditional
way,
and-
and
the
first
thing
I
I
need
to
do
is
do
a
deconvolution
so
for
the
convolution,
I
need
to
create
an
object
mask
to
indicate
where
I
want
to
decompose
an
image
and
then
I
I
also
need
to
create
local
support.
It's
a
stomach
where
I
don't
want
to
sharpen
or
you
know,
become
blue
and
then
I
also.
F
We
also
need
to
create
psf
image
to
indicate
your
star
and
so
it
and
I
did
not
use
and
o3.
I
did
acquire
them,
but
I
I
try
to
bring
the
into
the
image,
but
I
it's
not
quite
well,
because
I
think
I
need
I
need
to
work.
I
need
to
learn
more
how
to
do
that
and
so
and
then
so,
when
I
do
the
kombucha
deconvolution.
F
F
So
this
is
a
terrible
in
my
from
my
houses.
It's
a
lot
of
light
pollution,
so
I
you
know
I
crop
little
bit
and
I
do
the
dynamic
background
extraction
so
and
I
one
when
so
when
I
when
I
had
doing
processing
I
my
my
pistol
inside
crashed,
so
I
don't
have
trac
record
for
the
project,
so
so
what
I
did
here
right
so
first
I
started
the
convolution.
So
let's
go
to
here
so
usually
with
this.
We
need
to
see
here
with
a
view
of
sorry.
F
F
Yeah
a
little
bit
small
and
during
the
combustion
right
I
need
to
local
support.
I
need
to
make
I
expand
the
star
right
to
protect.
No
start,
I
don't
want
to
do
the
convolution,
so
I
I
keep
up
like
I
keep
expanding
convolution
and
then
do
the
morphological
transfer
to
make
the
star
bigger.
So
to
prevent
me
to
you
know:
don't
do
that!
Do
not
apply
the
decompression
on
this
stuff,
so
everything
look
perfect.
So
then
I
start
to
okay.
F
F
And
I
I
think,
the
because
I
screw
up
this
stuff,
it's
a
because
when
let's
go
back
to
here,
go
let's
go
back
to
the
before
with
the
convolution.
So
this
is
a
screen
transfer
right.
It's
you
always
stretch
to
what
we
see
right,
but
when
we
do
all
the
a
stretch
weight
some
here,
it
no
longer
applies
same
as
quality
in
the
screen
transfer.
It's
different!
That's
why
we,
this
stuff,
are
getting
worse.
F
F
F
F
F
F
F
F
F
A
F
For,
oh,
I
usually
if,
if
right
now,
this
weather,
I
tell
them,
but
I
keep
the
scope
but
take
down
the
camera
so
and
then
I
use
I
I
use
two
layer
of
edge.
I
use
a
garbage
bag.
I
use
two
side
of
garbage.
First,
I
carpenter
garbage
bag
right.
I
put
rub
along
the
scope
and
the
second
garbage
bag
put
under
the
tripod,
and
then
I
had
a
big
telescope.
F
F
A
A
F
B
F
F
I
suck
me
my
image
and
they
like
this
one
and
yeah,
and
this
one
is
the
ho
and
I
think
the
process
is
the
same,
and
this
is
a
straight.
I
do
a
lot
of
so
it's
it's
a
pretty
similar
to
what
I
did
a
dolphin
head,
yeah,
so
yeah
this
one's
pretty
good
yeah
and
I
also
had
a
very
good
way
to
continue
for,
like
eight
day
night
day
we
only
and
this
one
right,
because
the
weather
is
so
good.
I
keep
everything
I
don't
even
turn
my
camera
at
all.
F
D
F
F
F
Supreme
they,
they
sent
me
a
print
24
by
16.
wow
and
it's
pretty
good
yeah.
And
so
I
I
so
the
at
least
when
I
I
think,
do
you
see
that
this
one
right?
I
have
one
problem
the
host
telescope
slip
down
and
because
of
this
one
right,
I
tire
and
keep
straight
down
and
and
however,
it's
still
dying
very
well,
because
the
low
pass
is
heavy
and
it's
still
guide
very
well
and
no
problem
at
all.
B
F
So-
and
you
know
I
I
try
to-
I
think
you
try
to
make
a
scope
parent
right.
You
know
here.
I
oh,
I
had
some
weight.
I
clicked
here,
but
it's
still
not
quite
work.
It's
already
free
spin,
but
60
head
encoder
right.
It's
it's
quite
good
yeah
and
also
this
one
is
the
white
field.
You
don't
require,
you
know
and
it's
it
was
every
piece
I
I
like
in
code
and
I
had
a
problem
this
one.
F
C
F
I
I
try
to
solve
the
same
problem
here.
If
I
don't
put
it,
it
was
the
whole
telescope
would
spin
right,
left
and-
and
so
I
put
here-
and
this
gold
right
is
actually
started
getting
better
recently,
because
I
finally
use
the
multiple
star
guiding
on
the
phd2
and
it
gets
better.
So
it's
allowed
me
to
image
and
d1
for
me
had
a
much
longer
expo
time.
Yeah,
it's
it's
quite
quite
nice
yeah
and
I
I
spent
about
two
years
to
make
it.
I
also
changed
the
focus.
F
F
So
I
you
know,
I
spend
a
lot
actually
this.
This
said
I
spend
a
lot
of
time
and
and
also
I
change
a
lot
and
so
and
for
the
ceiling
40.
I
just
put
it
on
and
walk
no
christian.
I
it's
it's
wonderful
yeah.
I
I
I
was,
I
was
praying
for
this
one
for
for
a
roller
outside,
go
to
a
dark
side
and
because
it's
small
everything
easy
to
set
up-
and
I
also
show
you
it's
a
tec.
F
F
You
know
it's
otherwise,
no
way
for
me
to
image
at
this
part,
so
yeah
this
one
and-
and
this
also
encoder
sometimes
right-
I
I
visually,
then
I
change
it
to
image,
and
then
I
forgot
to
balance
and
then
it
it
just
sky
very
well,
just
like
a
cem
40
like
I,
I
don't
even
know,
I'm
I'm
not
in
the
parents,
so
yeah
this.
The
monk
with
the
encoder
is,
is
a
really
good.
Yeah.
F
A
C
Yeah,
so
I'm
hoping
to
get
back
out
in
the
field
and
have
people
come
out
to
little
yuvas
I
just
as
we
were
talking
here.
I
was
trying
to
see
if
there
was
any
indication
on
the
santa
clara
county
website
about
the
covid
situation
regarding
outdoors
and
I
didn't
see
anything
super
specific
for
other
than
you
know,
outdoor
sports.
They
have
a
whole
special
page
for
that,
but
I
did
go
to
the
open
space
authority
and
it
looks
to
me
like
there
all
their
trails
are
open
at
this
point.
C
I
call
it
a
poor
man's
onag
right.
Originally
it
was
3d
printed
and
now
I've
moved
on
to
modifying
a
inexpensive
flip,
mirror
it's
a
little
more
precision
in
terms
of
being
made
out
of
metal
instead
of
plastic
and
stuff,
and
so
that's
the
current
project.
But
the
idea
is
to
you
know,
use
the
the
on
egg
for
guiding
and
focus
control
with
that
rig.
C
C
C
C
C
The
board
had
thought
originally
that
that
was
too
much
risk
for
people
just
show
their
driver's
license
and
then
take
off
with
you
know,
ten
thousand
dollars
worth
of
worth
of
stuff
and
and
also
the
fragility
of
you
know,
dslrs,
which
is
what
we
had
at
the
time,
but
I
think
their
attitude
may
have
changed.
I
mean
now
there's
solar
rigs
in
the
program
which
are
sort
of
similar
in
some
ways.
You
know
in
terms
of
the
cost
anyway,
so
yeah
and
based
on
the
amount
of
gear
that
we
have.
Maybe
we
could.
C
C
Saying
you
know:
can
we
now
that
we're
in
the
red
tier?
Can
we
do
this
on
a
limited
basis
or
something?
So
I
think
we're
waiting
to
hear
back
on
that,
but
yeah
and
then
there's
always
the
the
idea
of
you
know.
Can
we
set
up
a
remote
site
somewhere,
or
you
know
what
people
would
be
interested
in
in
terms
of
a
club
subscription
to
telescope,
live
or
or
what
have
you
as
a
way
to
supplement
your
thirst
for
images
and
data
to
process
when
it's
cloudy
or,
however,
you
want
to
southern
hemisphere?
C
C
C
A
C
C
F
C
Could
just
add
for
the
for
the
selective
color
thing
from
that
that
website
yeah
I
made
a
photoshop
action.
I
think
I
shared
it
here
before
I
like
the
way
that
that
he
was
doing
it
with
I
took
notes
he
he
was
doing
it
with
adjustment
layer
so
that
it's
non-destructive,
which
is
different
than
how
my
action
works,
but
but
I
do
have
an
action
that
goes
through
all
the
steps
on
that
webpage,
with
one
click
green
to
gold,
yeah
green
to
gold
yeah.
Exactly.
C
F
C
F
A
F
F
C
C
Those
are
very
hard
to
to
come
up
with,
but
I
I
just
pulled
the
trigger
on
a
on
a
yellow,
narrow
band
filter
from
a
company
that
I
found.
So
I'm
gonna
try
using
h,
alpha
and
o3,
and
then
this
yellow
filter
to
do
you
know
galaxy
type
targets
under
heavy
light
pollution.
So
we'll
see
I
don't
have
any
idea
about
halos
or
anything
with
this
filter.
They.
C
C
A
C
C
C
Yeah
because
I'm
I've
got
six
nanometer
astronomics
and
the
club
has
those
as
well
on
a
couple
different
rigs
that
we've
got,
but
I'm
interested
in
trying
to
go
down
to
three
nanometer,
and
this
makes
it
a
lot
more
economic,
so
we'll
see,
I
want
to
see
a
few
more
things
on
astra
bin
and
a
few
more
most
most
of
the
discussion
on
cloudy
nights
was,
I
think,
comparing
them
to
the
to
the
better
wider
nanometer
filter.
So
we'll
see
yeah.
I
B
I'm
trying
to
improve
my
astrophotography,
I'm
not
there
yet
recently
I
got
an
asi
1600,
a
lrgb
and
I'm
having
a
problem,
I'm
supposed
to
spend
more
time
trying
to
fix
it,
but
it's
been
a
little
while.
So
the
problem
is
when
my
luminous,
when
I'm
taking
pictures
at
the
very
beginning,
seems
to
be
okay.
A
B
A
B
You
know
and
then
later
on,
when
I
try
to
process
my
pictures
and
I
see
that
all
the
luminos
are
all
white,
just
the
luminance.
Yes,
reds
are
fine
green
but
because
I
don't
have
luminosity.
Quality
of
the
pictures
are
not
that
good,
okay,
I'm
probably
gonna,
have
to
move
to
the
show,
but
I'm
not
there
yet.
So
I
just
wonder
if
people
have
the
same
type
of
problem
and
how
they
fix
that
issue.
C
Yeah
we're
confused
by
the
fact
that
it
seems
like
it's
just
happening
to
the
luminance
right.
So
scts
are
kind
of
you
know
the
the
poster
child
for
for
doing
up
when
the
weather
conditions
cause
that
so
yeah
a
dew
shield
or
and
or
a
dew
heater,
but
that
doesn't
explain
why
you're
only
seeing
it
in
the
luminance
unless
there's
something
weird,
where
it's
actually
there's
moisture,
condensing
on
the
luminance
filter
and
not
the
other
filters
which
doesn't
really
make
a
lot
of
sense
to
me.
Either.
B
B
C
B
A
People
who
might
have
experience
with
something
specific
like
that,
then
we
don't
okay.
I
wish
I
could
tell
you,
but
we
are
very
fortunate
at
this
point
to
be
able
to
have.
You
know
something:
resources
like
that
that
we
can
ask.
We
can
put
a
question
up
there
and
get
responses
from
people
all
over
the
world.
You
know
thousands
of
people
will
see
it.
G
G
Yeah
there
are
a
selection,
obviously
one
that
you
can
get
and
I'm
running
the
velocity
11
and
it
helps
out
in
two
ways.
First
of
all,
it
would
go
up
very
quickly
about
a
six
months
out
of
the
year,
but
the
other
thing
it
does
it
doesn't
help.
It
helps
in
a
big
way
to
control
extraneous
life
from
getting
into
your
objects
where
it
bounces
around.
G
Okay,
so
so
it
has
a
it
has
a
cooler,
but
also
has
a
heat
window
on
it
on
the
camera
itself.
For
that
you
have
a
possibility
of
putting
in
a
filter
that
is
colder
than
that
heated
window,
so
it
may
be
pulling
in
moisture
as
to
prepare
preferable
place
to
be
dued
upon.
So
I
would
kind
of
look
at
those
things
and
then
one
thing
you
can
do
as
a
diagnostic
is
when
you
think
okay,
this
is
about
the
time
of
night
that
this
happens.
G
You
know
the
front
surface
for
the
schmidt
and
just
shine
down
there
and
see
if
on
any
of
your
optical
surfaces,
you
are
getting
due,
don't
be
too
armed
about
weird
dust
and
all
that
stuff
that
happens.
But
if
you
have
dew
on
any
of
those
surfaces,
you
may
be
able
to
see
it
and
then
be
able
to
localize
the
issue.
G
A
B
G
I
B
F
B
F
B
F
I
also
had
an
asi
1600,
so
I
don't
have
a
problem
and
one
night
about
I
think.
Last
year
this
time
I
tried
to
do
a
coordination,
so
I
take
the
dual
heater
out
and
I,
when
I
do
a
coordinating
and
like
five
minutes
my
my
my
phone
press
or
got
a
lot
of
deals
right
away,
yeah,
it's
very
easy
special
this
time
so
yeah,
that's
what
I
had
before.
A
One
thing
that
I've
also
seen
is
some
new
shields
are
more.
You
know,
I've
seen
people
make
due
shields
and
they
were
a
little
more
flexible
than
was
workable
and
if
they
change
in
their
shape
a
little
bit.
Your
flats
may
not
be
consistent
if
you're
doing
flats
to
compensate,
and
you
want
to
get
a
dew
shield-
that's
pretty
stiff.
