00:00:00
in the first part of this geology we
00:00:02
looked at the basic things of Nina how
00:00:05
to install it how to set it up how to
00:00:08
connect the equipment how to change some
00:00:10
settings and how to do some basic
00:00:12
shooting now in the second part we look
00:00:15
at sequencing
00:00:21
hey this is few into space I'm Sasha
00:00:24
from Switzerland security McDonald's and
00:00:27
thanks for watching my channel so what
00:00:28
do we know our sequencer was known until
00:00:31
a few months ago as the advanced
00:00:33
sequencer but what is a sequencer
00:00:36
a sequencer is an automation tool
00:00:39
because that's really what we want from
00:00:41
Nina we do not want to care about all
00:00:43
the nitty-gritty stuff which has to be
00:00:46
done we want to let Nina do that and go
00:00:48
peacefully to watch TV or sleep or
00:00:51
anything else that's more interesting
00:00:53
that's standing freezing beside your
00:00:55
telescope
00:00:56
and while the sequencer might look a
00:00:58
little bit complex at the very start I
00:01:01
will guide you now through it and at the
00:01:02
end of the video it will not be that
00:01:04
scary anymore and after a few times
00:01:07
practicing it will be daily routine
00:01:09
let's jump now right in the PC and let's
00:01:12
have a look in Nina
00:01:15
so welcome to Nina again so let's assume
00:01:18
we have already connected all of our
00:01:20
equipment the next thing we do we go to
00:01:23
Sky Atlas and we want to look for
00:01:25
something we want to shoot something in
00:01:27
this light we want to shoot the player
00:01:30
these so we enter here M45 we search for
00:01:34
it and here it is so we see that's
00:01:37
actually wonderful it's right on sinus
00:01:41
at the moment Let's ignore that it's
00:01:43
daylight
00:01:44
so we say set for framing assistance and
00:01:49
here it is the player this so it fits
00:01:52
wonderful in my 400 millimeter scope
00:01:56
you can still move it a little bit
00:01:58
around and yeah that looks great let's
00:02:00
do it like this so now that I have it
00:02:02
actually framed the way that I want I go
00:02:05
here add Target to sequence and I have
00:02:09
now two options either I can say a
00:02:12
Target to sequence or I can say add
00:02:14
Target to Target list so let's first of
00:02:17
all move it to a Target list I can then
00:02:20
state of which sequence and we will look
00:02:23
at that in a second so I'll put it now
00:02:26
there so I can now go and actually look
00:02:29
for something else let's say I also want
00:02:32
to look for Orion also here framing
00:02:35
assistant
00:02:36
and here we have Orion this I think
00:02:39
actually looks better if I do it
00:02:41
vertically so let's move it around great
00:02:44
and I do the same again at the Target
00:02:47
list
00:02:48
move it to my sequence we will see in a
00:02:52
second How We Do sequences and it's done
00:02:54
now let's remember that we have done
00:02:56
that and we leave that at the moment as
00:02:59
it is and now we go here in sequencer so
00:03:03
in the sequencer we have actually
00:03:05
instructions
00:03:07
we have templates
00:03:10
and we have targets
00:03:12
and when we go to targets what you see
00:03:15
m42 and M45 so the two which we just
00:03:20
entered now right where we want it
00:03:23
already framed so these are our targets
00:03:25
and so we can store all the targets that
00:03:28
we actually want to shoot at one point
00:03:30
of time the wave frames that we want to
00:03:32
shoot him already here so we have them
00:03:34
ready now when it comes to sequences we
00:03:39
could start now from scratch but you
00:03:42
know it's a little bit like with
00:03:43
everything why reinvent the wheel so so
00:03:47
I did not start from scratch I took some
00:03:51
templates from Patriot Astro actually
00:03:53
you still see them here but then I also
00:03:56
modified them to my taste and what I
00:03:59
will provide now to you isn't quite
00:04:02
altered template that I feel is the most
00:04:05
efficient but it's also most efficient
00:04:08
for my case again it might be very
00:04:10
different from you and so that
00:04:12
definitely also go to Patriot Astro he
00:04:16
has really a lot of different templates
00:04:20
that you can actually use but we take
00:04:22
now the template that I will also
00:04:24
provide to you and let's throw this now
00:04:27
in here just drag and drop and as stated
00:04:31
at the beginning this looks now
00:04:33
extremely complex and confusing
00:04:36
and what we're doing now we go step by
00:04:39
step
00:04:40
through the script
00:04:41
and you will see that it's not that
00:04:44
confusing at all and also very easy to
00:04:48
modify so the first thing you have to
00:04:50
know if you want to delete this template
00:04:53
again you go on the very top to this
00:04:56
trash pin if I click it the whole thing
00:04:59
is gone again if you modify anything on
00:05:02
this script we're not talking about the
00:05:03
object we just talk about anything else
00:05:07
if you modify anything just click here
00:05:10
on this button on the floppy disk and it
00:05:14
saves it and before we go any further
00:05:17
you might have one question rightfully
00:05:19
so how do I actually get these templates
00:05:22
to appear here good question let's jump
00:05:25
over to options and in options to
00:05:28
Imaging and you see here sequence and on
00:05:31
the second line here you see sequence
00:05:33
templates folder that's a folder that's
00:05:36
already there by default you could
00:05:39
change it but on the other side you can
00:05:41
also leave it exactly where it is so
00:05:44
just find this folder on your hard drive
00:05:46
and throw the template that you download
00:05:50
either from page with Astro or from me
00:05:52
and just throw it in here and as soon as
00:05:55
you have done that you will find it in
00:05:58
the sequencer on the templates here and
00:06:00
you can use it and so also every time
00:06:02
you save a template for example a
00:06:05
version from what you have done it will
00:06:08
simply go in here and also be in the
00:06:10
folder that I just shown you so let's go
00:06:12
back so we have our template you know
00:06:15
now how to close it how to save it so
00:06:18
the next thing you will see is a lot of
00:06:21
these red marks here and what they state
00:06:25
is that whatever should be used here is
00:06:28
not connected which is quite obvious
00:06:30
because I'm not outside so for example
00:06:33
my telescope my camera is at the moment
00:06:36
not connected and that's very helpful
00:06:39
because once you configured it you need
00:06:42
and there might be things you don't even
00:06:43
have like for example a filter wheel so
00:06:46
these you will all delete
00:06:48
but at the end when you have your
00:06:49
template with your equipment if you
00:06:52
actually go in the template to fill it
00:06:56
in for the night and you see any of
00:06:58
these red signs still appearing it means
00:07:01
something you have forgotten to connect
00:07:04
it's a very good sign to still connect
00:07:07
it until every least one of these is
00:07:10
disappeared so a sequence is actually
00:07:12
red from the top to the bottom so we
00:07:16
start at the very top and the very top
00:07:19
actually gives us the object the Target
00:07:22
that we want to shoot
00:07:24
at the moment there's nothing in there
00:07:26
and we can now go to these targets which
00:07:29
we saved before
00:07:31
and we for example say we want to play
00:07:34
these and 45 we take it and throw it in
00:07:38
here and it's in here now it will shoot
00:07:41
the Pleiades if we change our mind
00:07:44
we want to shoot Orion we take this drag
00:07:47
and drop
00:07:49
now it's Orion
00:07:50
so whatever is up here is the one thing
00:07:54
that will be shot there is by the way
00:07:57
another way to do that if we go back now
00:08:01
to the framing assistance where we have
00:08:03
been remember here Orion
00:08:05
I can also say here add Target to
00:08:07
sequence if I click that
00:08:10
and I say sequencer I can choose here
00:08:13
from all the templates that I have
00:08:16
I click on it automatically this
00:08:18
template will be opened and you go into
00:08:21
the sequencer and you have exactly the
00:08:24
same picture as you have right now so
00:08:27
now let's go down and you see now that
00:08:30
we have certain blocks
00:08:32
they always start with a header for
00:08:35
example here it says equipment ready so
00:08:38
what we do in this block is get the
00:08:40
equipment ready and then there's three
00:08:43
groups the first one is triggers
00:08:46
and the trigger where we don't have here
00:08:48
one is something that has to happen that
00:08:52
it triggers something for example if
00:08:55
temperature goes down and autofocus is
00:08:58
triggered next is Loop conditions
00:09:01
if you want to Loop something that it
00:09:04
happens again and again and again
00:09:06
we stayed here until when this should
00:09:09
Loop for example until a certain time or
00:09:13
until the moon gets up and so on also we
00:09:16
don't need that here and then next come
00:09:18
the instructions so let's now see what
00:09:21
we instruct our rig to do first of all
00:09:24
we tell it to wait wait until 40 minutes
00:09:28
before astronomical dusk so then then we
00:09:31
start with the preparation
00:09:33
then please unpark the scope then set
00:09:36
the tracking to side rail then cool the
00:09:39
camera to -10 degrees Celsius once this
00:09:43
is done put the two heater at the camera
00:09:45
on switch the filter in the filter wheel
00:09:47
to an opt along L Pro so that we're
00:09:50
definitely not on a narrow band filter
00:09:52
for plate solving and then do a plate
00:09:55
solve and sync it with the scope and
00:09:58
then our first box is complete now you
00:10:01
might say
00:10:03
um find Sasha but I don't have a filter
00:10:04
wheel no problem
00:10:06
you go to this line here and you see the
00:10:09
trash bin
00:10:10
just throw it in the trash gone your
00:10:12
camera doesn't have a do heater no
00:10:14
problem
00:10:15
gone and I'll just show you how to
00:10:17
delete things but afterwards I also show
00:10:20
you how to add things okay so then we
00:10:23
have here a Waits time again so when it
00:10:25
when this is completed the rig has to
00:10:28
wait again until we are 20 minutes
00:10:30
before astronomical dusk then we go on
00:10:33
with the preparation of the target
00:10:35
so we ask now the rig to slew to the
00:10:38
Target
00:10:39
based on the target we entered on top of
00:10:42
here
00:10:43
and Center on it so it will now slew
00:10:46
plates off and ensure that it's within
00:10:49
the tolerance that we already given once
00:10:52
this is done we ask that the guiding is
00:10:54
started we can also say if a calibration
00:10:57
has to be done each time and that's in
00:10:59
principle if you leave your guide scope
00:11:01
alone
00:11:02
it's no need if you only need to do it
00:11:04
the first time and then we ask you to do
00:11:07
an autofocus again if you have an
00:11:09
electronic autofocuser otherwise you
00:11:12
know how to delete it once it's all done
00:11:14
we are centered on the target we are
00:11:17
guiding we are in Focus so we're
00:11:20
actually ready in principle to shoot But
00:11:24
It's Not Dark Yet so we wait until it's
00:11:27
about 10 minutes before astronomical
00:11:29
dusk and that's now the time when we're
00:11:33
ready to shoot and now comes our
00:11:35
shooting sequence here and now here you
00:11:38
see a lot of triggers and also Some
00:11:40
Loops so what do we State here in the
00:11:42
triggers we state that please autofocus
00:11:45
after an HFR increase so if the stars
00:11:49
get bigger by an amount of 10 percent
00:11:52
then please autofocus again because that
00:11:55
might one of the reason why we have a
00:11:57
bigger HFR also please autofocus after a
00:12:00
temperature change
00:12:01
every time the temperature changes by 2
00:12:04
degrees it autofocuses then we also tell
00:12:07
it to Center off the drift so this will
00:12:10
be evaluated after each exposure and if
00:12:13
the drift is bigger than two arc minutes
00:12:16
it reads loose so that we're always
00:12:18
exactly at the same place and if there's
00:12:22
anything that stops the clock hiding
00:12:24
like the re-slowing and so on WE State
00:12:27
restore The Guiding before we start
00:12:29
shooting so these are all the triggers
00:12:31
now there's a loop we State please shoot
00:12:35
continue shooting until it's nautical
00:12:38
done because then it's not dark anymore
00:12:42
so please stop shooting and now finally
00:12:45
finally
00:12:46
we are ready to shoot
00:12:48
and what I give you in my template are
00:12:52
three shooting sequences if you have
00:12:54
different filters or one different
00:12:57
exposures but again if you do not need
00:13:00
all three you can delete them now
00:13:03
there's only two so in each line we
00:13:06
State now what we want and this is every
00:13:07
time obviously different so for example
00:13:10
here
00:13:12
we State we want to have 50 pictures
00:13:15
by 60 seconds these are lights
00:13:20
we leave the binning at one gain and
00:13:24
offset is already entered by the camera
00:13:26
settings
00:13:28
filter if you have a filter wheel you
00:13:30
can choose it now for example for this
00:13:32
iucent Leo
00:13:34
and you want to dither every for example
00:13:37
two exposures afterwards I want to have
00:13:41
another 50 pictures also 60 seconds but
00:13:46
this time with the color magic filter
00:13:48
again I did every two time
00:13:52
and that's it so what's going to happen
00:13:54
now it starts shooting after each photo
00:13:58
it takes it goes up here did the edge of
00:14:02
our change did the temperature change
00:14:04
did we have a drift
00:14:06
and if it has it autofocuses or it reads
00:14:10
loose
00:14:10
and then it continues every second photo
00:14:13
it did There's once it has down the 50
00:14:16
pictures here it goes down that's the 50
00:14:19
picture with the other filter
00:14:21
and now you know what happens there's a
00:14:24
loop so if there's still enough time it
00:14:26
goes up again here starts to shoot again
00:14:29
with the unclear then with the color
00:14:31
magic and so on and it does this Loop
00:14:34
until there's nautical Dawn and once
00:14:37
nautical Dawn comes it jumps down here
00:14:40
then we say please stop guiding now
00:14:43
Park the scope now as I have an eagle
00:14:46
five I can also say it to stop to do
00:14:49
heater then it warms the camera up and
00:14:53
once the camera is warmed up I also
00:14:55
switch off the energy to the camera to
00:14:58
save electricity to save the camera and
00:15:01
then my sequence is done and nothing is
00:15:04
happening anymore
00:15:05
so that is a whole sequence and as you
00:15:08
can see it's not that difficult
00:15:11
especially when you already have such a
00:15:13
template now but what if you want to add
00:15:16
something for that we go to instructions
00:15:19
and you will see there's a lot of
00:15:21
instruction and actually there's even
00:15:23
more if you go up here on this icon you
00:15:27
see some icons that are red and these I
00:15:31
actually
00:15:32
this activated so you can go down
00:15:36
and you can say oh I don't have a dome
00:15:38
for example
00:15:40
because I don't have a dome so you just
00:15:42
click on them
00:15:44
that they're red and they will not
00:15:46
appear so you only leave the one which
00:15:49
have some relevance to you everything
00:15:51
else you just cross out and at the end
00:15:54
you click here the icon again
00:15:57
and so you really only work with the
00:15:59
stuff that you want to work with now for
00:16:01
example you say well actually
00:16:05
right after the autofocus here I want to
00:16:07
already take one exposure so just as a
00:16:10
test exposure then I see how it will
00:16:13
look like so we can actually go here say
00:16:15
take exposure by the camera
00:16:18
and I just take it
00:16:20
and drag and drop throw it in here see
00:16:22
time it's also 60 seconds and that's
00:16:26
done another example you might have a
00:16:28
mount where you need to do a Meridian
00:16:30
flip so you go here to telescope you see
00:16:32
here Meridian flip it's this Arrow which
00:16:35
means it's a trigger and I just throw it
00:16:37
here by the triggers
00:16:39
and so it will be done when it's
00:16:41
actually needed when and how to do a
00:16:44
Meridian flip you're already defined in
00:16:46
the settings and there are also easier
00:16:48
things for example here Loop until time
00:16:50
instead of an article down you can also
00:16:53
say sunset or you can simply enter time
00:16:56
sometimes I do that if for example I
00:16:59
only want to shoot one object and at one
00:17:01
point this actually is too low to shoot
00:17:04
then I choose Center here the number
00:17:06
until two o'clock in the morning for
00:17:08
example now it shoots until then so I
00:17:11
really encourage you to play around with
00:17:13
this and really look at them it this is
00:17:15
not a program language this is really
00:17:18
all clear text and even there are a lot
00:17:21
of things you can actually change it all
00:17:24
makes pretty much sense if not you see
00:17:27
there's some help text which explains it
00:17:29
to you and so you will get the hang of
00:17:31
it pretty fast now you might have the
00:17:34
question so what if I want to shoot two
00:17:36
Targets in one night you can actually
00:17:39
use more than one of these sequences so
00:17:42
you go all down I go back to templates
00:17:44
take my default again
00:17:48
and I just throw it below now here I
00:17:51
would now enter Target
00:17:54
I would argue I would enter another
00:17:55
Target and there's obviously now a few
00:17:58
modifications which you have to do
00:18:00
mostly that you would actually delete
00:18:03
here the first sequence or the end part
00:18:07
it's gone there's also a few things
00:18:11
in the second one which you do not have
00:18:14
to do anymore the wait time on Park all
00:18:18
this stuff the whole equipment you can
00:18:20
actually delete that but once you have
00:18:22
done that
00:18:23
everything's fine so Loop until time so
00:18:26
you stayed Now by time until when it
00:18:30
actually should Loop for this first
00:18:32
object and as soon as it's finished here
00:18:35
it goes down into the second sequence
00:18:37
and starts to shoot there and so you can
00:18:40
do that with as many objects in one
00:18:42
night as you want to
00:18:44
so I hope you agree that it's not that
00:18:47
difficult and from now on your computer
00:18:50

00:18:53
safe time the template that I mentioned
