Description
This month we're very excited to have Alexander Curry of Telescope Live presenting on their advanced remote observatories. Alex will be talking about their facilities and the different programs available to the public.
Alex has been part of the Telescope Live since it's early days, helping setting up the very first telescopes. He's an amateur astrophotographer and is responsible for customer support, tutoring, and user experience. He also helps with the overall operations.
B
So
I'll
just
give
you
a
small
sort
of
talk
through
the
bits
and
pieces
of
our
platform
and
then
I'll
give
you
a
small
demo
as
well
of
them
kind
of
things
that
we
do
so
there's
just
a
sort
of
couple
of
stock
images
from
from
our
platform,
users
they're.
I
think
the
majority
of
these
are
what
we
call
one
click
observations
which
I'll
come
on
to
in
a
minute.
B
B
So
this
is
our
network.
We
have
our
site
in
chile,
we
have
I'm
gonna,
say
five
or
six
telescopes
here
now
I'll
go
through
the
list,
so
we
have
our
60
centimeter,
which
is
a
cdk
24
plain
wave
telescope.
We
have
our
one
meter,
asa
telescope.
We
have
the
two
50
centimeter
sa
newtonians
and
then
we
have
a.
I
think
it's
a
sigma,
200
millimeter.
B
Prime
lens
and
all
these
telescopes
are,
apart
from
the
the
sigma
camera
they're
all
on
fly,
pl
16803,
which
is
a
full
frame
camera
and
use
astrodon
filters
as
well.
So
we
we
aim
to
offer
people
the
the
highest
quality
optics,
along
with
the
then
best
images
that
you
can
get
from
these
telescopes
by
putting
them
in
locations
that
are
all
dark
skies
sites.
B
So
it's
a
chile,
for
example,
we
have
seeing
which
averages
below
one
arc
second,
and
we
have
somewhere
around
320
to
330,
clear,
like
clear,
knight,
sea
gear
there
so
tons
of
imaging
time
and
the
the
quality
of
images
as
you'll
see
I'll
show
you
some
raw
frames
later
on
that
we
get
back,
are
just
fantastic,
so
we
have
our
observatory
in
spain
and
in
spain
we
have
three
telescopes
at
the
moment,
so
you'll
see
on
the
right.
We
have
a
top
right.
B
We
have
two
takahashis
in
spain
and
spain
as
a
site
itself.
We
ravages
between
one
and
one
and
a
half
arc
seconds
of
seeing
night
or
night,
and
I
think
we
are
averaging
around
300
nights
per
year
of
clear
skies
at
the
moment,
however,
than
the
over
sort
of
january
february,
the
the
skies
aren't
as
favorable
as
some
terrible
nights
and
we've
actually
had
the
audition
of
snow
over
the
last
few,
a
few
weeks,
which
is
quite
unusual
for
the
area.
B
But
you
know
this
is
what
we've
been
given
and
then
we
have
heaven's
mirror
in
australia,
which
we
currently
just
have
the
takahashi
106
there
again
with
fly,
pl-16803
camera
and
the
astronaut
filters
seeing
is
a
lot
more
stable.
We
get
between
1
and
1.2
arc
seconds
of
seeing
and
a
very
similar
between
300
and
310
clear
nights
a
year.
This
is
actually
martin
pugh's
site
for
the
people
who
have
probably
met
him
at
the
imaging
conference
in
san
jose,
maybe
last
year
or
whenever
before.
B
So.
These
are
the
three
observing
modalities
that
we
offer.
We
have
the
one
click
observations,
the
pro
data
sets
and
the
advanced
requests.
Now
I
was
just
talking
to
bruce
briefly
before
everyone
joined
about
sort
of
what
we
can
offer
for
clubs,
and
it
really
depends
on
what
you
as
a
society
want
to
use.
B
So
the
the
one-click
observations
we
kind
of
offer
on
a
on
a
per-person
basis
and
I'll
show
you
on
the
platform
in
a
little
while
how
they
work
pro
data
sets,
as
you
can
imagine,
is
just
raw
data
effectively
bundled
of
some
popular
and
not
so
popular
targets.
We
really
sort
of
try
to
vary
it
and
you
can
download
that
data
and
process
it
yourself
and
then
the
advanced
requests
is
the
sort
of
more
manual
and
direct
control
of
the
telescopes,
and
so
you
use
list
as
some
this
example.
B
B
So
I
think
here,
oh
yep,
another
thing
we're
offering
so
our
one
meter
telescope,
I
think
one
meter
36
inches
or
somewhere
around
that
mark
this
massive
telescope
in
in
chile.
We're
going
to
be
offering
planetary
observation
with
that,
so
that's
a
new
mode
of
observing
it
says
here
january
2021,
we've
had
a
few
technical
hitches,
you
may
or
may
not
know
who
damien
peach
is.
I
know
he's
very
popular
here
in
the
uk.
He
shoots
lots
of
great
images
of
the
planets,
which
is
a
few
on
screen
here.
B
So
here
I've
now
got
a
few
images
that
I've
taken
these
and
I
don't
want
to
in
any
way
say
that
I'm
a
professional
at
this,
but
this
is
orion.
Obviously
I
slightly
over
exposed
the
core
here.
This
was
two
300
second
exposures
in
luminous,
red,
green
and
blue,
and
this
was
when
I
was
testing
out
the
functionality
of
the
one
click
observation
functionality,
and
so
really.
B
So
another
one
I
have
here.
This
is
the
great
bard
spiral
galaxy.
I
shot
this
recently
from
the
one
meter
telescope.
I
was
pretty
pleased
with
how
it
came
out.
It's
a
nice
nice
looking
galaxy.
This
was,
I
believe
I
think
this
was
three
five
minute
exposures
in
red,
green
and
blue.
Only
and
I've
got
some
some
nice
details
about
this
one
and
then
one
of
my
other
favorites
I
have
next
is
etta
karina.
This
was
taken
using.
I
think
it's
with
the
cdk24
in
chile,
hydrogen
alpha
s2103.
B
Obviously-
and
this
was
this-
was
slightly
more
exposure
time.
I
think
I
spent
maybe
half
an
hour
in
each
filter
and
it
gave
me
pretty
pretty
decent
results
or
results,
rather
that
I'm
fairly
happy
with
anyway,
so
this
is
sort
of
a
flavor
of
what
people
what
I've
been
producing
with
the
platform
anyway
and
I'll
show
you
our
gallery
in
a
second
as
well,
so
you
can
see.
What's
you
know
what
we
have
to
offer
there?
B
B
So
we're
not
always
going
to
be
observing,
you
know
all
night,
long
from
dusk,
till
dawn,
and
so
what
we
do
is
we
create
observations
that
are
available
to
be
picked
up
by
people
who
are
registered
to
our
platform
and
these
don't
actually
cost
anything,
it's
the
end
user.
So
we
have
three
subscription
tiers,
bronze,
silver
and
gold,
and
it's
four
dollars
for
the
bronze
19
for
the
silver
and
fifty
four
dollars
for
the
gold
and
with
all
of
these
you
have
access
to
the
one
click
observations.
B
The
only
thing
that
you're
limited
on
is
the
number
of
pending
observations
that
you
can
have
at
any
one
time.
So
if
you're
on
the
bronze
plan,
it's
four
dollars
a
month
you'll
have
you
can
have
two
pending
observations:
the
silver
it's
15
and
then
the
gold
is
unlimited,
and
we
we
create
these
large
lists
of
observations
over
a
couple
of
weeks,
and
so
you
can
go
in
and
we
repeat
objects
as
well,
and
so
what
we
do
is
we
take
a
30
minute
window
where
we
observe
a
target.
B
B
Look
at
the
tarantula
nebula,
we'll
observe
that
for
30
minutes
in
either
hso
or
just
rgb,
and
then
you
receive
that
data
the
next
day.
So
I'll
just
give
you
an
example
here.
If
we
go
to
new
observation,
these
are
all
the
targets
that
are
currently
waiting
to
be
imaged
there'll,
be
some
that
will
be
running
right
now
in
spain,
maybe
not
depending
on
the.
B
If
the
weather's
cleared
up,
for
example,
we've
got
karina
nebula
here,
so
if
I
click
observe
now
that
image
will
be
taken
in
four
hours
time
and
returned
to
me
and
so
for
the
people
who
are
coming
into
astrophotography
on
a
budget.
This
is
great
because
over
the
course
of
a
couple
of
weeks
they
can
build
up.
B
A
B
B
B
That's
that's
a
good
point,
so
we
do
run
calibration
on
all
the
images
that
come
in.
We
run
calibration
frames
pretty
much
around
the
clock.
I'd
say
when
we're
not
observing,
there's
also
time
made
for
the
calibration
frames,
and
these
are
automatically
reduced
from
the
images.
However,
with
that
said,
you
can
actually
download
the
uncalibrated
frames
yourself.
So
if
calibration
is
a
part
of
your
process
that
you
have
a
particular
method
or
something
that
you
would
prefer
to
to
do
yourself,
then
of
course
that's.
You
know
entirely
for
you
to
do.
Okay,.
B
B
So
you
see
here,
there
are
color
images,
and
these
are
just
previews
of
of
what's
been
observed
on
that
from
that
data
set,
and
so
hopefully
the
idea
is
that
yours,
you
have
this
preview
image
you'll,
be
able
to
download
the
raw
data
and
produce
something.
That's
you
know
far
greater
than
you
know
there
are
algorithms
have
done
for
you,
so
the
next
thing
that
we
have
is
the
pro
data
sets.
B
So
these
are
just
big
big
data
sets
and
these
are
accessible
for
the
silver
and
gold
plans
and
depending
on
which
plan
you're
on
it
sort
of
dictates
the
the
sort
of
the
costs
or
the
equivalent
cost
of
this
data
set.
So
if
you're
on
the
silver
plan,
you
have
all
the
standard
plans
available
to
you
and
they're
all
for
free
as
well
they're,
all
included
in
your
plan
and
for
the
gold.
B
So,
to
give
you
an
idea,
this
two-hour
statute
of
liberty,
nebula
data
set,
would
have
cost
about
300
credits,
which
is
about
300
dollars
to
observe,
and
it's
taken
with
the
cdk24
in
in
chile
and
there's
a
two
hour
data
set.
So
it's
you
know
these
are
healthy
data
sets
that
are
available
for
you
to
to
download
and
to
to
to
work
on,
and
that's
really
what
we
you
know
really
want
to
push
here.
Is
that
all
the
data
that
we
produce?
B
This
is
how
this
is
the
interface
with
which
you
control
them.
So
this
was
what
our
platform
originally
looked
like
or
the
original
left
of
our
version.
One
we'll
call.
It
was
just
the
sort
of
direct
control
we
didn't
have
any
of
the
one
click
observations
or
the
the
pro
data
sets,
but
this
this
is.
This
is
how
this
works,
so
you
put
in
any
name.
You
know
like
orion
m42,
anything
like
that,
and
you
will
get
the
coordinates
for
you.
You
can,
of
course,
make
adjustments
to
the
coordinates.
B
Australia
and
spain
have
either
pretty
poor
observability
or
large
queues
and
I'd
say
it's
probably
a
mix
of
the
two
and
the
weather
included,
and
you
can
choose
any
of
these.
We
don't
really
discriminate
the
telescopes
based
on
what
is
suitable
for
your
target.
So
if
you're
going
for
a
particularly
small
galaxy,
we're
not
going
to
not
suggest
or
not
put,
you
know
the
takahashi
refractors
on
there.
This
is
purely
because
this
should
be
treated.
B
B
B
Oh
it's
also
worth
pointing
out
just
quickly
while
we're
here
with
the
advanced
tab.
You
also
get
access
to
the
photometry
filters
or
you
should
have
some
reason.
This
telescope
doesn't
have
them,
but
all
of
our
majority
of
our
telescopes
have
photometry
filters.
So
if
you're
into
hunting
exoplanets
or
anything
like
that,
we
offer
that
as
well.
We
are
also
moving
towards
perhaps
doing
various
spectroscopy,
but
we're
working
on
a
way
to
integrate
that
into
our
platform.
B
So
back
to
the
astrophotography
tab:
this
is
you
know,
you
choose
your
filters,
you
choose
the
exposure
time
and
the
exposure
count
and
that
automatically
adds
them
all
to
the
side
here
so
you'll
see
here,
it
says:
overheads
37
minutes.
Now
we
do
charge
for
the
overheads,
which
is
the
telescope
setup
time
the
filter,
changing
and
download
time.
B
B
Custom
is
more
similar
to
what
I
would
say
our
competitors
offer
so
you're
you're,
given
the
the
available
spot
here
of
m42,
you
just
drag
and
drop
the
the
the
observing
session,
so
there's
only
just
shy
of
the
the
two
hour
17
or
the
it's
actually
just
started
anyway.
So
this
is
not
usable,
but
if
we
go
ahead
to
the
next
night,
there's
a
nice
big
block
here,
so
I
can
drag
and
drop
this
in
here.
B
Now
the
other
option
we
have
is
the
automated
scheduling
and
what
this
does
is
this
uses
our
own
personal
built
algorithms.
This
is
something
that
marco
has
worked
on
to
produce
and
what
this
does
is
it
takes
your
mood,
avoidance
preference.
So
if
you're
imaging
in
narrowband
in
particular,
you
can
set
75
moon
elimination
is
what
we
kind
of
suggest
is
don't
go
about
that
really,
because
the
quality
of
the
images
can
significantly
degrade
beyond
that
and
what
we
offer
is
a
moon
discount
so
see
here.
B
80
minus
86
credits,
so
you
know
huge
chunk
of
a
discount
on
the
actual
plan
itself
and
what
the
automated
shuttling
does
is.
It
takes
your
observation
and
it
breaks
it
down
into
individual
frames.
So
if
you're
imaging
three
luminance
you'll
break
those
down
to
three
individual
luminance
observations
and
it
will
schedule
those
and
integrate
those
with
the
current
schedule,
so
we
optimize
for
observability
and
observability
windows.
B
B
Similarly,
if
your
plan
fails,
we
can
due
to
poor
psf
or
artifacts
or
any
cloud
interference.
We
can
take
those
individually,
effective
affected
frames
and
re-observe
them
without
losing
your
priority
in
the
schedule.
So
it's
a
really
flexible
way
for
us
to
control
the
schedule
of
the
telescopes,
while
also
maintaining
you
know,
good
observability
and
good
results
for
all
the
the
the
targets
that
we're
observing.
B
So,
after
that
we
can
hit
the
next
step
and
then
the
observation
is
ready
to
be
sent
off,
so
you
can
click
confirm
and
that
sends
it
to
the
telescope
and,
depending
on
what
you've
selected
you'll
receive
an
email,
giving
you
a
notification
when
it
starts
and
when
it
finishes
so
you'll
know
you
have
a
rough
idea
of
how
it's
progressing
over.
You
know
course
of
a
couple
of
weeks.
B
B
B
I
shoot
a
lot
of
a
lot
of
time
on
that
telescope.
As
you
can
see,
this
is
something
like
ic443.
This
is
a
raw
500.
Second
frame,
it's
there's
a
small
pre-stretch
automatic
stretch
applied
to
it,
although
that's
obviously
not
the
one
that
you'll
download,
and
so
you
can
select
these
images
like
that.
So
I'll
just
pick
those
four
images
and
I
can
download
them
and
they
will
be
sent
to
the
download
requests.
B
So
in
here
we
have
a
list
of
your
downloads
and
the
reason
we
do
this
is
kind
of
in
a
staging
methodology.
So
because
the
database
is
so
big
and
we
keep
all
images
that
everyone
observes
indefinitely,
sometimes
it
could
take
us
a
while
to
file
and
sort
these
images.
Just
here
just
said,
the
the
download
is
now
ready.
So
if
I
refresh
that
we
can
download
that.
B
Zip
folder
of
the
of
the
images
it
says
here
expires
in
13
days.
That
doesn't
mean
the
images
are
actually
going
anywhere.
It
just
means
the
r
saved
version
of
this
download
folder
that
we've
prepared
for
you
will
be
removed.
You'd
have
to
go
and
select
the
images
again.
Alternatively,
if
we
go
back
to
say
the
advanced
requests
go
on
my
requests
here
and
download.
As
the
fountain
is
completed,
these
are
completed.
You
can
download
the
entire
data
set,
download
the
calibration
frames
or
even
resubmit
it.
B
So
if
you
want
to
acquire
more
data,
so,
for
example,
the
the
bald
spiral
galaxy
that
I
imaged
a
few
weeks
ago,
I
would
consider
getting
some
more
color
data
from
that,
so
I
can
resubmit
that
with
just
you
know,
I
don't
have
to
go
through
the
whole
process
of
setting
up
a
new
observation,
so
that
also
brings
me
on
to
the
projects
side
of
things.
So
one
thing
that
we
and
we're
still
working
on
this
feature
itself.
One
thing
that
we
found
is
a
particular
annoyance
for
a
lot
of
people.
B
Is
you
have
all
your
data
saved
to
your
hard
drive
at
home,
but
there's
a
lot
of
times
where
you
know
you
can
observe
things
in
multiple
blocks
and
build
these
up,
and
so
what
we
can?
What
we
do
here
is
we
offer
folders
and
projects,
and
we
need
to
further
define
these
a
little
bit
better
to
make
them
a
bit
a
bit
more
user-friendly
because
he
heard
the
ngc6231.
B
So
I
have
all
the
data
for
this
saved
into
this
project
and
I
can
select
the
whole
lot
and
issue
a
download.
So
if
I
make
any
other
observations
of
this,
I
can
keep
adding
to
this
project
to
maintain
the
whole
lot
quickly.
Just
talking
about
the
the
data
archive
again
with
the
one-click
observations,
once
it's
clicked
once
these
are
finished,
you
can
access
the
the
data
or
the
original
data.
Rather
the
raw
data
from
the
data
archive
and
clicking
that
see
original
data
takes
you
here.
B
So
you
see,
you've
got
the
three
or
the
six
images,
rather
that
were
taken
on
that
in
that
half
an
hour,
so
the
other
side
of
the
platform.
This
is
a
completely
different
aspect
of
it
is
our
sort
of
public
pages,
and
so
the
things
that
we
offer
to
to
sort
of
create
a
community
around
telescope
live
and
the
images
that
people
produce.
B
So
we
have
the
gallery,
which
is
a
you
know
great
example,
of
all
the
images
that
people
have
been
producing,
and
there
really
is
some
excellent
work
that
comes
out
of
telescope
live,
especially
from
adam
block,
peter
jenkins
and
nick
simmonic
as
well.
They'll
produce
fantastic
images
that
go
up
in
the
gallery
and
you
can
see
just
some
of
the
work.
B
Obviously,
some
very
new
to
astrophotography
are
able
to
upload
their
data
as
well,
and
the
other
side
of
things
that
we
have
is
we
have
a
facebook
group
dedicated
to
the
telescope,
live
and
that's
a
you
know,
great
point
of
discussion
for
people
how
to
improve
techniques
and
things
like
that
and
are
our
tutors
as
we
call
them
or
partners
rather,
who
are
world-class
astrophotographers.
They
take
part
in
the
discussion
and
over
the
next
few
months,
we're
looking
to
develop
our
live
streaming
sessions
as
well.
B
B
Things
like
that
that
done
by
these
world-class
astrophotographers-
and
you
know,
they're
shared
to
be
able
to
to
educate
and
to
to
help
improve
people's
processing
skills,
and
all
of
this
is
included
with
the
you
know,
with
the
normal
subscription
for
telescope
live
so,
for
example,
adam
here
he
did.
He
ran
this.
B
I've
lost
the
preview
image.
Now
he
lost
this.
He
ran
this
very
obscure
galaxy
that
hadn't
really
been
imaged
before
he
ran
it
on
the
one
meter
telescope
in
chile.
I
think
it
was
something
like
35
or
36
hours
worth
of
exposure
time,
which
is
all
available
for
you
to
download
and
to
try
out
yourself
to
process
yourself
and
with
it.
He
made
a
four-hour
tutorial
on
how
he
went
about
processing
all
the
different
techniques
that
he
used
and
it's
broken
down
into
these
various
parts.
B
So
you
can
skip
through
and
you
know,
choose
and
go
to
the
bits
of
the
the
tutorial
that
you
see
relevant
to
yourself
and
then
finally,
is
the
the
blog
in
the
academy,
and
these
these
kind
of
things
are
more
for
the
public
outreach
and
they
are
it's
information.
You
know
around
astronomy
as
in
in
general,
so
you
know
what
groups
of
galaxies
emission
line
stars
things
like
that
and
so
they're
more
educational
side
of
things
that
we
offer.
B
B
You
know
astronomical
groups
who
are
just
interested
in
just
receiving
pro
data
sets,
and
so
we
have,
you
know,
an
agreement
between
us
and
them
in
order
to
deliver
the
pro
data
sets
to
them.
You
know
to
much
reduced
cost
compared
to
subscribing
the
entire
community
to
a
to
a
plan,
and
so
really
it's
up
to
to
you
as
a
community
and
a
society
to
decide.
B
You
know
what
aspects
of
the
platform
you
would
like
to
use
individually
and
what
aspect
of
the
platform
that
you
would
like
to
use
as
a
group,
and
with
that
I
would
say
that
we
do
offer
a
one
month
free
trial,
so
you
can
choose
the
bronze
or
the
silver
plan,
and
I
would
recommend,
obviously
the
silver
plan,
because
you
have
more
access
to
lots
of
different
things.
You
don't
need
to
put
in
your
your
card
or
payment
information
or
anything
like
that.
B
You
just
need
to
use
an
email
and
a
password
to
sign
up
and
you
can
try
stacking
up
a
ton
of
one-click
observations
for
an
entire
month
and
see
you
know
what
you
produce
with
them.
So
I
I
thank
you
very
much
for
your
time.
If
you
have
any
questions
just
saying,
let
me
know
if
you
have
any
questions
in
the
future.
I'll
leave
bruce
my
email,
so
you
can
just
get
in
contact
with
me
as
well.
C
C
You've
got
30
minutes
divided
up
among
four
filters,
so
you
have
very
short
exposures,
maybe
you're
having
two
exposures
per
filter,
so
you're
you're
not
getting
the
noise
reduction
ability
from
the
stacking
that,
if
you
so
one
of
our
one
of
the
things
that
came
up
is,
I
know
now.
I
am
a
one-shot
color
camera
user.
So
this
is
just
kind
of
the
way.
I
think
and
the
reason
I'm
one
shot.
Color
camera
user
is
because
I
don't
have
very
much
time.
B
Yeah,
so
I
I
I
understand
where
you're,
where
you're
coming
from-
and
you
know
it
is-
I
wouldn't
say
you
know
it's
kind
of
a
concern
about
you-
know
the
quality
of
the
data
you
would
receive
back.
However,
it's
worth
noting
that
the
telescopes
we
have
are,
in
especially
in
terms
of
in
chile,
are
in
the
clearest
skies
on
the
planet
right
or
some
of
the
clearest
guys
on
the
planet
and
the
quality
of
the
optics
that
we
have
are
you
know
the
cost
individual
cost
of
a
telescope?
B
Is,
you
know,
anywhere
from
a
hundred
thousand
dollars
up
the
the
one
meter
telescope
was
somewhere
in
the
region
of
two
million
dollars
in
order
to
be
installed
so
that
the
quality
of
the
data
you
receive?
Isn't
anything
like
the
quality
that
you
would
receive
at
your
own
with
your
own
setup,
and
so
you
can
actually
do
a
lot
of
work
or
a
lot
of
get
a
lot
of
mileage
out
of
these
short
exposures,
this
running
chicken
nebula
here
this
is
a
single
five
minute
exposure
and,
yes,
granted.
B
You
know
the
the
two
ten
minutes
or
two
five
minute
exposures.
When
you
go
and
stack
them
to
try
and
average
out
any
any
imperfections
or
to
try
and
get
the
signal
noise
that
you
require,
it's
you
know
half
the
leg.
Work
is
already
done
in
that
because
of
the
quality
of
the
optics,
the
instrument
and
the
skies
themselves.
B
However,
that
said
with
the
one-click
observations,
you're,
not
just
tied
to
that
single
request
right.
So
if
there's
one
running
chicken
nebula
request
here,
but
we
will
actually
schedule
over
the
course
of
two
or
three
weeks,
maybe
10
or
15
of
them.
So
over
that
time,
if
you
come
on,
you
know
twice
a
week.
You
can
pick
up
those
observations
and
you
know
by
the
end
of
this.
You
know
two
weeks
you've
got.
B
Sessions
absolutely
yes,
so
it's
it's
once
you
once
you
build
them
up.
You
know
from
that
point
of
view
you
can
produce
fantastic
results.
I'll
actually
show
you
through
the
gallery.
Instead,
this
is
a
really
really
good
example
that
I
had.
I
hope
I
uploaded
it
here.
No,
I
didn't
so
I'll.
Just
use
this
as
an
example.
So
this
this
was
of
piedes,
and
this
was
just.
I
think
it
was
just
two
five-minute
exposures
in
rgb
and
like
granted.
B
When
you
first
look
at
it,
it
is
you
know
it's
not
particularly
magnificent,
or
you
know
there
isn't
necessarily
the
punch
of
the
date
you
would
get
from
you
know,
maybe
an
hour's
worth
of
observation,
even
you
know
at
say
my
own,
my
own
home,
however,
for
10
minutes
in
red,
green
and
blue,
the
the
signal
to
noise
and
the
quality
you
get
out
of
it
is
huge,
and
so
I
think
this
is.
This
is
quite
a
a
mental
hurdle
that
people
have
to
to
overcome
and
it
feels
quite
unnatural
to
begin
with.
B
You
know
you're
observing
with
these
huge
telescopes
and
you
know
in
the
desert-
and
you
know
these
cliffs
guys
and
to
go
from
requiring
maybe
a
few
hours
worth
of
exposure
at
home
to
only
like
30
minutes
in
total.
You
know
it's
a
completely
different
ball
game,
but
you
know
granted
there
are
targets
out
there
that
require
a
long
amount
of
time,
but
for
the
majority
of
you
know,
messier,
cardwell
or
whatever
catalogue
you
go
for
named
named
targets.
D
Just
yeah,
it's
rob
just
a
quick
one.
What's
the
policy
on
say
a
spoiled
frame
like
if
cloud
rolled
in
and
ruined
a
frame
or
you
know
since
you're
talking
about
these
sort
of
stacks
of
like
one
or
two
images,
you
know
if
an
airplane
flies
right
through
and
you
can't
reject
yeah.
So
do
you
just
refund
that
or
is
it
just
tough
luck
or
what's
the.
B
No,
no,
absolutely
not
so
airplanes,
not
so
much
of
an
issue
is
more
satellite
to
the
issue.
When
we
have
people
who
are
requesting
large
data
sets
with
the
with
the
telescope
directly
so
say
you
want
to
observe,
you
know
m42
for
a
couple
of
hours
on
one
of
the
takashi
telescopes
and
you
have
a
satellite
trail
through
it,
depending
on
the
volume
of
frames
that
you've
observed,
we
may
suggest
you
know.
B
I've
spoken
to
several
people
who
have
used,
you
know
not
to
name
names
but
say
like
I
telescope,
where
they've
received
poor
data,
and
you
know
it's
they've
been
given
a
well,
you
know
that's
the
nature
of
our
hobby
and
yes,
and
no
that's
kind
of
you
know
what
it's
about,
but
we
do
want
to
provide
you
with
good
data.
So
if
you
have
an
image
that
is,
you
know,
you're
not
happy
with
the
focus
or
the
focus
degraded
over
the
course
of
your
observation.
E
Hey
this
is
hi.
I
have
a
question.
I've
never
used
any
remote
telescopes
before
so
I
have
this
sort
of
I
mean.
Please
don't
interpret
this
the
wrong
way,
but
just
like
help
me
understand
like
for
things
like
pro
data
sets.
You
know
why
don't
I
use
hubble
data
or
something
like
that.
If
we're
going
to
get
good
data,
let's
go
to
space,
you
know
what
is
yeah.
B
The
way
that
we
try
and
position
ourselves
and
to
sell
you
know
to
sell
what
we
do
it's
you
know
we're
in
no
way
trying
to
replace
the
home
hobby.
You
know
we
believe
everyone
should.
You
know,
partake
in
actually
doing
astrophotography
taking
your
telescope
out,
setting
up
a
mount
whatever
it
is
to
take
to
actually
do
the
physical
process.
B
B
B
You
know,
there's
current
events
in
astronomy
and
observational
astronomy
that
we
try
to.
You
know,
provide
access
to
at
the
same
time,
and
so
really
what
we
are
trying
to
offer
is
you
know
something
similar
to
you
know
using
hubble
space
telescope,
but
then,
but
you
know
nowhere
near
that
magnitude
of
cost.
B
But
you
know
that
that's
that's
what
we
try
to
to
aim
for
we're,
not
we're
not
in
any
way
trying
to
replace
using
hubble
data
or
trying
to
replace
using
your
own
home
setup
we're
trying
to
be
an
intermediate
access
to.
You
know
new
equipment,
new
skies,
you,
you
know
a
whole
different
world
of
astrophotography-
that
people
may
never
actually
really
be
able
to
access.
C
A
B
Absolutely
yeah,
so
the
majority
of
our
connection
is
done
through
satellite
at
the
moment,
so
whether
we
will
be
able
to
use
starlight,
I'm
not
too
sure
at
the
moment.
I
haven't
really
looked
much
into
it
in
terms
of
if
it's
been
affecting
the
images,
I
mean
for
the
volume
of
observations
that
we
do.
You
know
we
haven't
actually
had
that
many
frames
at
all
affected
by
them.
I
think
we've
only
had
a
very
few
number
that
have
been
affected.
B
You
know
in
a
week
on
week
period
and
honestly,
I
haven't-
I
haven't
seen
one
for
a
fairly
long
time
myself.
So
you
know,
as
as
the
project
picks
up,
maybe
we'll
see
more
satellite
interference
in
our
on
our
frames.
But
for
now
you
know
we
really
really
haven't
had
an
issue,
but
who
knows
in
future?
Maybe
it's
going
to
be
a
huge
problem
for
us.
Maybe
we've
just
been
lucky
so
far
I
mean
I
personally.
B
Obviously
I
mean
I'm
still
in
the
uk
at
the
moment,
but
when,
when
I'm
at
university,
I
have
my
own
setup
in
italy
and
I've.
I've
run
a
lot
of
observation.
You
know
night
or
night
and
I
I've
had
maybe
a
couple
of
frames
that
been
affected
by
it.
But
that's
that's
about
it.
So
maybe
this
location-
maybe
it's
just
luck,
but
no.
We
don't
have
much
interference
from
it.
Yet.
B
Yeah,
absolutely
there
is
so
there
is
a.
There
is
a
big
aspect
of
maintenance
to
our
mounts,
and
while
we
do
a
yearly
manual
or
physical
maintenance
to
them,
the
last
one
being
in
spain
towards
the
oh,
no,
it
would
have
been
about
a
year
ago.
Now,
in
spain
we
do
have
people
on
site
who
are
capable
of
cleaning,
maintaining
and
repairing
any.
B
You
know,
sort
of
issues
that
could
be
could
be
could
arise
and
these
people,
the
people
that
deal
with
these
telescopes
they
actually
are
somewhat
professional
in
their
approach.
I
think
so
that
they
understand
you
know
the
software
best
mounts
or
paramounts
inside
and
out
same
for
the
guys
in
chile.
They
understand
the.
B
I
think
we've
got
a
mathis
mount
there.
You
know
they
understand
that
now
inside
and
out-
and
so
you
know,
the
downtime,
if
something
were
to
happen
would
be
as
minimal
as
possible.
I
think
the
the
cdk24
the
plane
wave
we
have
hasn't
actually
been
touched
for
about
six
months.
Maybe
a
year
now
it
hasn't
been
attached
at
all.
It
just
runs,
starts
up.
Every
night
runs
its
imaging
run
and
then
closes
down.
All
completely
untouched-
it's,
it's
kind
of
you
know
mind-boggling
when
you
think
about
it.
B
B
We
actually
do
use
non-proprietary
non-proprietary
software,
so
that
maxim
we
use
for
the
image
acquisition
and
then
whatever
proprietary
software
we
give
them
for
the
mount
and
for
the
automation
side
of
things
we
use
custom.
I
think
it's
java.
We
use
custom
java
that
runs
the
acp
scripts
for
the
scheduling,
so
we're
using
acp,
but
it's
modified
heavily
in
order
to
do
what
we
want
to
do
with
it
and.
B
Guided
usually
off-axis
guiding,
we
had
an
issue
in
spain
where
we've
had
to
move
to
a
guide
scope
which
is
being
installed
soon.
This
is
for
the
big
70
centimeter
and-
and
it's
quite
horrifying
really
because
the
the
telescope
we
have
to
use
is
a
large
150,
millimeter
old,
mead
triplet
to
do
the
guiding
for
this
telescope
and
it's
you
know
compared
to
the
telescope
that
I
have
at
home.
You
know
it's:
it's
completely
different
ball
game,
but
yeah
it's
so
the
majority
of
them
are
all
well
yeah.
B
A
B
B
A
B
At
the
time,
however,
now
we're
seeing-
and
this
is
very,
very
common
with
these-
with
these
the
caf
sensors-
is
we're
seeing
some
degradation
in
the
in
the
center
itself,
which
is
producing
you
know,
one
dead
column
on
all
the
sensors
and
so
we're
looking
to
over.
You
know,
while
this
isn't
an
issue
to
actually
process
out
cosmetic
correction
in
pictures
inside,
for
example,
does
a
fantastic
job
of
dealing
with
these?
B
You
know
you
can
get
some
of
the
way
with
the
to
the
images
we're
looking
to
perhaps
move
towards
cmos
to
replace
them.
Now
whether
we
find
something
that
is
or
performs
as
well
as
these
cap
sensors
do,
and
actually
it's
worth
noting
that
these
the
sensors
themselves
kodak
have
stopped
reducing
them.
So
should
a
camera
actually
completely
go
or
you
know
we
can't
find
a
replacement.
We
wouldn't
need
to
look
for
an
alternative
and
perhaps
one
of
the
new.
I
can't
remember
who
produced
them.
B
Someone
produces
a
full-frame
cmos
sensor,
but
it's
something
to
the
tune
of
fifty
thousand
dollars
in
cost,
and
so
for
that
price
you
have
an
entire
takahashi
set
up
so
yeah,
that's
that's
where
we
are
at
the
moment.
We
we're
comfortable
at
the
moment
with
the
I
say,
we're
comfortable
with
the
degradation
but
we're
comfortable
with
where
the
sensors
are
in
that
they
still
produce
good
images.
The
the
bad
bad
columns
are
on
the
extremities
of
the
sensor,
they're,
never
in
the
in
the
middle
or
interrupting
the
sensor
in
any
way.
B
B
If
we
move
to
cmos
in
the
future,
perhaps
but
we'll
have
to
see
how
the
you
know,
there's
the
new
influx
of
cmr
sensors
that
are
coming
in
now,
that
are,
you
know,
high
performance
you've
seen
like
zwo
have
produced.
You
know
fantastic
steam
of
sensors
attic
I've
been
doing
it
for
a
long
time
as
well.
So
you
know
we're
completely
open
to
changing
the
senses.
B
G
G
G
G
G
G
G
G
This
down
here
is
actually
a
reflection
from
something,
but
I
toned
it
down
a
fair
amount,
so
it
doesn't
look
like
it's
like
an
artifact,
but
it
is
yeah.
I
have
another
one
that
I'm
working
on.
I
got
the
data
for
it
last
night,
around
gemini
there's
a
lot
of
reflection,
nebulae
around
there
right
next
to
it,
but
whether
I
can
actually
process
it
so
that
I
can
get
the
get
the
reflection
tone.
That's
won't
be
too
bad
would
be
kind
of
my
challenge
for
the
next
few
days.
G
G
G
G
G
This
is
kind
of
what
it
was
looking
like.
This
is
the
rise
apart.
This
is
the
nose
piece.
These
are
the
thumb
screws
that
I
tapped
in
here
and
there's
that
piece
of
aluminum
I
was
making
so
that
this
would
clamp
down
on
this
nose
piece
to
the
phosphate
director
in
a
very
christian
way.
How
rigid
I
found
in
the
last
two
nights.
G
G
G
Well,
here
we
go:
this
is
an
object
that
holds
pictures
of
because
he's
not
missing
that
velocity
just
broken.
When
I
was
a
visual
observer,
it
was
always
a
popular
one.
For
me,
this
is
the
monsieur
objects
m46
and
which
are
two
nice
open
clusters.
There's
another
open
cluster
up
here,
there's
another
open
cluster
down
here.
G
G
They
had
very
good
conditions
this
night
this
is
m47,
so
you
have
a
lot
of
poor
stars,
some
of
them,
obviously
not
long
for
this
world
blow
up
at
some
point
or
whatever
the
first
dude
so
and
with
the
camera
moving
out.
How
can
I
get
some
colors
out
of
these
out
of
the
one-shot
color
camera
that
I'm
using,
so
I'm
gradually
moving
on
that?
So
that's
kind
of
what
I
did
in
the
last
week
before
then.
We
had
some
lots
of
interesting
weather,
not
to
mention
the
lots
of
moon.
G
G
G
E
E
E
E
E
You
enter
your
longitude
in
your
latitude
over
here
where
it
says
I
don't
know
what
e-longitude
is,
but
anyway,
I
it's
roughly
our
longitude
and
latitude
and
a
date
in
this
case
you'll
notice,
I'm
setting
this
up
for
tonight.
I
don't
know
that
tonight's
good,
but
for
for
for
the
purposes
of
this
discussion,
you
know
2
8
well
today,
of
course,
is
february
7th,
but
all
these
times
are
in
utc,
so
they're
eight
hours
ahead
right
and
so
now
what
you
have
here
is
a
table
of
known
exoplanet.
E
E
E
So
what
that's
telling
you
is
that
this
star,
before
and
after
the
transit
is,
you
know
0.02
magnitudes
brighter
than
the
dimmest
point
during
the
transit
by
some
planet
right,
I
guess
the
planet
is
b.
In
any
event,
I
did
the
math.
You
know,
I
know
the
magnitude
equation
and
0.02.
I
I
believe
I
did
it
for
0.02,
so
I
could
be
wrong
here,
but
if
I
didn't
do
it
for
.02,
it's
0.01
or
0.03
was
about
10
adus
out
of
a
thousand.
E
E
So
I
guess
you
need
repeated
exposures
and
whatnot,
but
there
you
go
it's
a
magnitude,
12.8
star,
so
yeah!
Well,
whatever
you
know,
I
guess
that'll
affect
the
exposure
length
and
and
then
of
course
you
know,
let's
see
this
one
begins
at
1
am
so
that's
not
gonna.
No!
No!
This
is
1
00
p.m,
so
that
would
be
3
a.m.
E
No!
No!
No!
What
is
that
yeah
12
13
minus
eight?
That
would
be
5
a.m.
This
one
doesn't
cut
it
right
because
it
starts
at
5
00
a.m.
If
I
have
this,
oh
no,
no,
but
this
is
february
7th.
For
some
reason,
if
I
go
to
february
8th
anyway,
you
get
the
idea
right.
We
could
find
one
that
has
let's
say
I
don't
even
know
if
this
is
a
good
one
for
sure.
Okay,
we'll
try
this
karate
one
here
with
0.025
at
at
at
4.
E
So
that's
at
8
pm,
8,
30
pm
tonight,
it'll
start
and
about
two
hours
later,
it'll
finish
and
it'll
go
down
there.
So
anyway,
I
thought
I'd
play
around.
You
know,
and
I'm
gonna
of
course,
of
course
pros
do
this
and
they
use
their
two
meter
telescopes
and
six
meter
telescopes
to
do
that,
but
what
the
hell
I'll
try
my
0.1
meter
telescope.
E
What
do
you
think
should
I
be?
If
I
take
enough
measurements,
should
I
be
able
to
detect
a
0.025
drop
in
magnitude
off
a
office
star?
That's
my
question.
This
is
my
little
science
project.
Last
time
we
were
talking
about
science
projects,
so
here's
my
little
science
project
attempt
in
a
few
months
I'll
report
back
and
let
you
know.
H
Yeah
well,
we
had
the
the
high
school
twins
in
the
club,
they're
they're,
probably
now
well
through
their
college.
Okay,
that
did
exoplanet
stuff
and-
and
if
I
recall
properly,
they
were
actually
collaborating
with
nasa
on
the
tool
chain
and
contributed
some
some
things
to
that.
So
there's
probably
the
the
the
on
the
website.
I
don't
think
we
recorded
that
presentation,
but
I
think
there's
some
information
on
the
the
family
website.
That
might
be
helpful.
E
I
can
find
the
star
I
have
its
coordinates,
I
mean,
hopefully
I
can
find
in
fact,
by
the
way
I
didn't
show
it,
but
if
you
click
through
here
on
wasp
10b,
you
know
here's
a
picture
of
the
star
and
there
it's
transits
over
the
next
10
months
right.
So
you
know
this
is
doable.
You
know
like
if
you
know
I'm
retired.
I
got
time
on
my
hands.
You
know
it's
doable.
I
can
take
the
pictures.
I
can
somehow
try
to.
E
E
You
know,
because
you
know
you
can
have
changes
in
the
the
flux
due
to
sky
conditions
and
whatnot.
So
what
you
do
is
you
take
the
the
background
stars
measure,
their
flux,
assume
they're,
not
you
know
they're
on
average
going
to
be
static
and
and
then
you
compare
that
to
your
target.
So
anyway,
I
think
it's
doable.
I
mean
I'm
not
going
to
do
any
science.
I
will
you
know
that
hasn't
been
done
before.
I
will
say
that
many
of
these
transits
were
originally
detected
by.
You
know
camera
lenses
right.
E
A
I
know
alex
philippenko
from
berkeley,
has
some
scopes
up
at
the
lick
observatory
area
that
are
automated
sky
survey
scopes.
Looking
for
exoplanets,
I
think
that
the
twins
glenn
was
referring
to
were
using
kepler
data,
that
was
public
data
pool
data
and
it
was
not
really
mined
the
way
that
it
could
have
been
or
you.
C
A
A
A
E
A
A
E
E
I
I've
heard
it
like
you
say
it's
hard
to
deal,
you
know
to
figure
out,
and
certainly
you
know,
doesn't
sound
like
a
match
if
you're
interested
in
some
wide
field
thing
to
use
hubble
data
right.
That
sounds
crazy,
because
the
hubble
focal
length
is,
you
know
quite
long,
but
it
does
seem
like
if
you
want
high
quality
data
you're,
not
taking
it
anyway.
E
H
H
There's
you
know
27
filters
or
something
that
that
hubble
has
and
just
understanding
you
know.
Finding
red
is
the
first
challenge
right
right
and
then
you
know
which
camera
was
it
and
which
configuration
and
which
you
know
area
of
the
sky
and
all
that
so
yeah.
It's
it's
it's
a
challenge
that
you
have.
G
C
D
I
I
do,
but
I
don't
use
any
of
the
stuff
that
you're
talking
about,
because
it
seems
to
be
centered
around
trying
to
sort
of
organize
your
stuff,
and
I
have
my
own
scheme
for
that.
But
you
know,
like
you,
were
saying
what
it
does
do
is
it
adds
xisf
and
fits
support,
sort
of
as
first-class
file
formats
in
the
finder,
so
it'll
go
and
there's
actually
a
plug-in.
D
D
It's
a
necessity,
because
for
whatever
reason-
and
I
don't-
I
never
understood
this-
but
there's
some
problem
with
spotlight
and
and
fits
files
when
you're
using
like
an
nfs
share
like
you-
just-
cannot
even
search
for
file
names
properly
if
the
data
is
all
on
a
on
a
like
af-s
or
nfs
server,
so
that
plug-in
actually
enables
me
to
search
my
nas
for
sub
exposures
that
my
telescope
has
put
there.
Otherwise,
I
have
to
use
you
know
the
shell
to
find
them,
which
is
kind
of
silly.
But
that
may
be
a
me
problem.
A
F
F
F
F
F
F
F
F
The
galaxy
is
nice,
as
I
love
this
galaxy
as
lots
of
interesting
h2
regions
in
the
in
the
spiral,
arms,
and
it's
always
a
it's
incredibly
blue
compared
to
the
other.
You
see
there
are
other
field
galaxies
that
are
this
elliptical
one
is
yellowish.
This
one
is
yellowish.
This
one
is
actually
in
the
same
same
group
as
m101,
so
it's
I
think
it's
responsible
for
the
distortion
of
the
arms
that
we
can
see
here
and
also,
of
course,
m101
is
responsible
for
the
distortion
of
these
arms
but
yeah.
I
like
the.
F
F
That
I
had
shared
last
time:
oh
okay,
yeah.
Oh
sorry,
the
one
that
I
sorry
my
bad,
the
one
that
I
sent
via
via
email,
creating
so
much
commotion.
Yes,
right,
yeah!
Let
me
let
me
get
it
if
this
one.
Yes,
nice,
yeah
this!
This
was
lots
of
work
to
process,
but
I
think
I
described
it
in
the
in
the
thread.
F
So
if
you,
if
one
day
we
you
we
are
interested
in
looking
on
a
step-by-step
guide
to
vissen
parise's
technique,
we
can
do
it
sounds
great
yeah,
it's
a
kind
of
a
problem,
the
only
problem
that
I
have
with
the
technique.
It's
not
really
a
problem,
but
it's
one
of
the
requirements.
You
must
have
a
wide
field
imagery,
and
so
I
think,
with
my
focal
length
the
ideal.
F
F
Who
was
I
follow
him
on
on
astrobin
and
he
takes
incredibly
large
mosaics.
He's
currently
working
on
a
54
panel
mosaic
of
the
milky
way
between
taurus
and
orion,
and
he
was
imaging
that
night
and
pretty
impressive
gear.
He
uses
a
rainbow
rainbow
astronomy.
I
believe
it's
the
manufacturer,
mount
rst
135
is
is
not
a
worm
gear
and
a
ring
wheel,
drive
it
uses
a
harmonic
drive.
F
So
the
capacity
is
about
30
pounds
without
counter
weight
and
goes
up
to
40
pounds
by
adding
a
small
counter
weight
which
he
had
that
night.
So
he
had
the
two
mirrorless
cameras
with
two
sigma
art,
135
millimeter
and
a
mini
pc
and
the
guided
telescope
mounted
on
the
on
the
lost
mandy
plate
of
this
mount
and
he
was
shooting
away
with
two
cameras
at
the
same
time,
pretty
impressive.

I
noticed
that
he
hasn't
posted
much
recently.
Probably
he
switched
to
a
different
hosting.
I
can
only
imagine
because
in
2021
he
published
an
incredible
mosaic
between
from
sophia's
all
the
way
to
at
least
to
cassiopeia,
maybe
perseus.
Even
let
me
see
if
I
can
find
it
on
some
other
hosting.
If
I
remember
what
he
uses.
