and whats ur scope
RedCat 51
yeah but then its def not the same
aperture wise
you can just be having a smaller sensor
Dslr
yeah which means a crop which means smaller resolution
Man sorry guys
I just am not having much luck with the weather
But I promise promise to image the next few weeks if clear
i dont think any more pleadies until next year, im having clear skies next week but that probably my lest chance to get orion
Pleiades is at zenith for my but can’t really shoot broadband due to LP
What about ha?
Not sure how my framing will work
where/how do u want me to share my 19.5hrs stack (Ha)?
i wont be able to add more data most probably
Yess, I try sharing the one drive link first so that if it works it’s already done, if it doesn’t I’ll share it tomorrow with wetranfer
Hello. I was able to get another hour of Ha data. I've combined it and uploaded to google drive. (it's total of 4 hrs now)
I tried stretching it real far and I can finally make out some of the structure so hopefully this is helpful 
Hey guys @late umbra @frigid patrol @blazing lake @flint sage @haughty iron @robust salmon I just got off talking to some people on r/ap and basically what they said is what we’re trying to do with this ha from B4,6,7,9 is literally impossible we need to be in B1 new moon skies to get meaningful data we can contribute. So at this point in time, or at least what I’m gonna start doing is focusing on particular IFN regions and dump hours of broadband data into it, basically just shoot broadband and forget ha. Until we can get a hold of someone who has a remote rig and clear skies, we can’t get the ha tail
@mighty raptor as I was typing this you came to mind, would you be willing to shoot a bunch of ha data on M45?
@modest estuary dont use r/ap as only opinion btw
I’m talking to rougereversal, Eigen, Jimmy and Sinpah
because you listen to them it would be always to reccomend a beginner a takahashi with mono
But what they’re saying makes sense
Does anyone know who took the original image that contains the Ha tail?
He/she might have a post or video on how they did it
That’s true we already have more than 15 hours on Ha and it’s still basically unusable
How much ifns around the region
Impossible? Sounds like a challenge.
Just kidding. I'll go shoot bodes galaxy like everyone else 
I'll hold off on going for Ha for now. Thanks for looking into it @modest estuary
@modest estuary
he said he shot Ha from bortle 8 so let r/ap stop bitching about needing bortle 1 for that
he just has 62 hours of Ha , with 8min subs thats why
Did u check out the Ha we have so far? Because looking at my 17.5hrs stack I’m pretty sure that if we get to let’s say 30 to 40hrs (maybe with 10 shot in monochrome) we can pull out something, maybe not as much detailed as the original one but for sure we get enough data to “build” ours…
(Sorry if my English is not perfect)
What's his filter though
l extreme
Ah that's not very narrow
well its not 3nm yes , but its still pretty good
Yes, I meant it's not extremely narrow
yeah
check-in
check-out
For the next week, I can't do anything since the telescope is getting fixed.
After that though I'll have to see. It is getting quite late into the season for M45...
Today is a clear night!
I am currently imaging, I hope I can detect at least a little Ha
Nope 
how long was this?
3-4 hours
I know I am expecting too much at F7, but I hoped to at least see something
Hmm guys
What do you think if we call it done
Pleiades will only get lower, and we have good amounts of integration, albeit my Ha was disappointing 
Lol yeah, I think we’re done
Let me check on r/Ap it any1 wants to contribute data
You should choose a target that’s still low in the sky but rising over the weeks, gives you time to plan everything out
Also I should get tracked soon so I'll help you guys this time 
If its not a target too big
What about NGC 225 as the next target, I haven't seen many photos of it but with a lot of integration time, there is some really nice dust in that region
It's also relatively close to Polaris so that may help get longer exposures
Like Leo triplet or markranian chain
Looks cool
But too low rn
Make sure it's both a broadband and narrowband target, those are the best ones
But honestly I'd just leave it to the BAT for this lol
Bat be doing not so great targets rn
#suggest-a-target
also pleiades is a pretty dull target too in my opinion...
I love m64 too, but I don't know how many have high enough fl for it or be interesting
But it has a lot of different interesting features, the detailed core, the outer ring and some fainter dust
Guys this isnt bat, keep the targets reasonable for most people ok
Why wouldn't it be reasonable?
M64 is not a particularly hard target
this isnt very reasonable
Wait, so you guys are up to do another target?
Thought everyone lost their motivation lol
Hell yeah though, I would be up to do another target that is much lower in the sky
Shame, would have loved to do it
This is the fainter ifn for those that have the gear, others can focus on the galaxy itself
And it's only a proposition...
Of course!
I can get the ifn :)
250mm+183MC pro
It would be nice to have a spreadsheet with everyone's gear
Yup, but let’s get to processing the M45 first
why would he contribute?
@rich bluff
I asked him if he did but I didn't understand his answer lol
i think the purpose is to find the sharpest best m45 data, not just add integration..
135mm f/2.8
4h of eh is nothing when total image is 70+h
And he got dust
@rich bluff show ur data on m45
@lusty zephyr @lilac dawn did you guys upload your high fl M45?
stack or subs?
@mint quartz
both
@old bobcat we’re calling it ends btw, so whatever data you got, upload it to the drive when you can
It costs nothing and can improve by at least a bit (with weighted stacking of course)
@crystal gazelle (so many pings ik) but I know you have M45 data, we’re calling it quits so if you could, upload the data you have (doesn’t have to be HA) when you can
yeah no
weighted stacking will remove trailing data
ill send my flats too
@frigid patrol could I post the drive link in here, it’s easier
yes it will
I guess we're not talking of the same thing
if you put 100hours of data and remove 10%... thats 10hours
and yes removing 10% of bad data on a 100hour dataset is fully reasonabke
Weighted stacking put different weights for each image depending on its noise level
It weights it, not remove it
im talking measured weight stack with everything included the best of the best, fwhm, star shape, noise etc
Yeah we're not talking of the same thing
im talking actual stacking not measuring
I'm zipping my data rn.
Me too?
less is more in big datasets / sharp is better than soft high snr
Anyway
yeah who am i too speak..
Uhhhhh stack not subs lol
I could never get in data that didn't have terrible seeing
Or was through clouds
And then moon came
lux asked for subs
.
i did indeed, @rich bluff share the best ones tho
to compare if its actually worth stack8ng them or not
Just upload the linear stack lol, we’ll use it if it’s good
lux just told me to send the exposures and stack so im doing what I was asked
well that is in #1021002743080558642 right now
alright data is uploading. You'll have the subs and all that stuff by around 6pm @late umbra @modest estuary
Never got around to it, sorry 😕
just send like 3 of your best subs
why
All good :)
yes
and 3 subs cuz its better than u sending pentabytes of data
yeah lol
alright i have to let DSS register the files for it to grade them so you'll have your 3 subs in about 20min
make that 7pm
Yeah ofcourse
Ig the way I contribute to the group is processing?
sorry dudes that I wasn't able to capture anything 💀
Same
I feel hypocritical that I asked everyone else to gain data
But getting none on my own
i swear to god
this is going to take ages
@late umbra @modest estuary heres the #1 best sub
ill send the other two
2nd and 3rd best in that order
Alr so here was the reference we agreed apon
why whats the point
combining 1200mm and 135mm aint worth it imo
how would you even do that
you dont for a reason lol
@rich bluff
Okay
I cant do anything about that
I know theres coma
yeah stop to f4 i assume will fix that
theres still coma down to f5.6
it never really goes away it just gets slightly better after each stop
and I also dont use those smaller f stops unless im shoot clusters, as for targets like this I use f2.8
(this was f2.8)
i know
but is that stopped down already or ?
because u are using apsc right ?
no
that means this will show coma even if you put a tiny sensor like a 585 on it
either way still not that good even wide open on apsc
so it is stopped down
im not because that much coma ... everyone else is free to use it
fair enough
that hurts pretty bad but alr
I wasted so much money on that piece of garbage lol
50ed..
Could u download my stack (13h Ha OSC) btw? Because if u still want it and u didn’t download it yet I have to send a new link..lemme know pls
ye sure send link
im pretty sure i put it on the drive tho
https://1drv.ms/u/s!AnDipg6PgQQAgp5ZKHXuMF55iEbrDw
Hopefully it works
I actually agree with lux here lol, no point combining worse data with better data for an extra 4 hours integration
It raises an interesting question that has been asked about the BAT too, wouldn’t some images be better if only the person with the best data’s images were used? That’s why so many who contribute to the bat don’t have their data used in the final image
Damn, I just had a dream that I was stretching my Ha and I saw a bunch of of the ha structure 💀💀💀
So depressing
But thats beside the point
Was everyone able to post the stacks on the drive?
star aberrations and FL
lux cant use jack's data cause its high fl
and lux cant use my data cause theres slight coma
Nah, ur coma is quite intense if you ask me
Ya it is
My FOV is similar to Orbit's
Very similar
Orbits data cant be used either
ye I have no purpose for being here either
we've got basically the same fov lol
i mean.. better ota will fox that
do you think I have money for that
Im jobless and parents wont help me
ok than dont get anything perfect what you already have
customize
idk shoot targets at f2.8 and stop to f8 for stars idk
be creative
Yeah that FL is totally fine
About what the group was about?
The idea is basically like the bat, except much smaller and just for fun
rn we just collecting data on M45
yes but this looks like you have bloating
Yii budget scope and cam, so it's not perfect. If it's usable I can upload it.
Well it's too narrow for this target but maybe it will be useful for the next one (we haven't decided yet which one)
the data is good for what you have but the stars bloating will make the already sharp stars in current data obsolete
Makes sense.
We should choose a galaxy
I was down to do the black eye galaxy, but ig its too small
Yeah I had the same idea
We should do a spreadsheet with everyone's gear
I might join
Pinwheel? Still kind of small but doable imo
Or bode and cigar (even if it’s getting kind of late for these)
it has ifn next to it so...
The Bat already did it so probably not the best choice 😅
And same
Oh right, didn’t think about that 🙈
What about coma berenice? I dont remember it's size
Markarians chain or something else?
Oh yes that's it
Most of the galaxies are a little lacking in detail just because there elliptical galaxies but there are some with nice structures.
It has potential I believe.
@frigid patrol I’m getting one more person to contribute some data
Just an idea.. we can do M81 M82 IFN ..
Lol B4 and lower 100%
Apologies for the text wall, but we all will need to come to a resolution on what to do.
Because Pleiades will only get lower and lower in the sky, there is not much chance on getting more useful data on it. And because of this, we should soon move onto the processing phase, where we all could combine our stacks, then produce a final master image of Pleiades. So if possible, if you have any data on Pleiades, please upload it to the drive! (It is fine though if you don't have anything though)
Now for Processing and Editing, it will take a lot of trial and error to combine all our stacks into one master. I hope that it won't be a huge problem, though it may take a while to figure out. Once we DO get the final though, what we could do is each edit the data by ourselves, then compare to others. Then the image we all liked the most can be chosen, and then refined to make a final image.
I do hope that in the future, if anyone is fine with staying, we would be able to someday another (Much more organized and well thought hopefully) project on A second target!
Thank you all for being in the group!
Nice! Where can I find the link to the drive?
@long estuary here's the link
I have another suggestion for the next target, m63
It has the bright detailed core with some ha in it and a fainter halo
Community for astrophotographers
This is with a 5inch
Maybe it's too small though
And the halo: https://www.astrobin.com/ru40fg/H/?q=ngc 4651
@blazing lake @lilac dawn @late umbra I dont think anyone else is going to upload data, so lets hit it, if one of you guys could provide the stacked of all the data that would be great
hold
I could li that maybe, I need to get OAM done first
@late umbra @blazing lake @lilac dawn ok now hit it, thomas uploaded his M45 data, check the LRGB folders
Stack data
Background Narrowband and Broadband are often thought of as completely independent fields of astrophotography; generally, for this reason, a target will be imaged in either one or the other, but this is far from the true reality of the situation. Nearly every target in the sky has some component of
This may be useful if we want to attempt ha addition
you could use my data 
Not really tbh, sorry
I never wished I had a reducer so much until now 
But yes, it is probably best to move on to stacking and processing If we can somehow avoid the artifacts
Uh I'd like to try stacking but some files are in pix format 
im sorry im going through some stuff i dont have time for this project processing part 
Sorry to hear that, it's obviously not a problem if you can't help and I hope everything's is going to be ok for you
Thanks 
I’ll give it a go at some point, been a bit busy this week
all good, I have a couple more people uploading as well, so try to hold off this week
So where are people mostly located? It would be much easier to choose a target if we knew...
Would be great to have a spreadsheet with everyone's location and equipment
Il try today or tomorrow in combination
Hi I also do this with many people how’s yours going?
Ded chat
when are we gonna stack the data and get to see the final image
I’ll try next week, been busy lately and I’m not even sure where to start from 🙈🙈🙈
I am downloading the data right now, we will see how pixinsight stacking reacts
Do u plan on giving PI all the data at once and stay stacking all at once?
Yes, but I am still downloading right now so it will be a while
pixel math
I know I’m really late but you want to trim the image down after aligning no?
yeah so that causes no black line, instead you only see the difference in amount of data, 15h in that corner vs 60h or something
cuz people shot without the same rotation cough hermit cough cough
l,mao
@blazing lake do your magic stacking pls
maybe if I feel like it lol
its quite the hassle
@frigid patrol where exactly is the upload folder? I might try to stack all of the data
I think all the data is in the osc folder
3 files I saw
and ha, and more in L, R, G, B
I'd love to help but some files are in xisf and I don't have pix :/
u can ignore that file
there should only be 1 xisf
@proven chasm help us 🙏
read my guide under M82-M81 image post on astrobin
@frigid patrol @modest estuary @late umbra I went ahead and stacke the OSC stuff we had (would've done the mono too but it wasn't working well) Here's the Stack: https://we.tl/t-yOZH486RJo this is Vikram's, Lux's, and my data
hmm frick, it has a bit of a line
heyyyy I think I fixed it
https://we.tl/t-VqBruGx8TK Here's the new stack
@blazing lake i just spend 30min downloading the first one UUUUUUUHGHGGAHSHAHAAHGAGAG
@blazing lake WHAT HAVE YOU DONE
U didnt read my guide then
Looks like some bad pixel rejection 
Sigh it literally says in my guide to not do that because ur lacking the data to do it
Read it
And one last thing it may not mention but should be obvious imo if ur not using pixel rejection…crop ur frames before aligning…u dont want the fked data at the edge of the fov
Uhhh
That’s… the same stack as we had…. 3 months ago 
We may want to figure out how to include the mono data
yo guys how is this mass integration doing?
oh dear
it had some funky magenta stuff on the stars
Ah
Did u read Stefan’s guide
mmm no not really lol
how about someone else do it 
idk man it just takes a lot of time to do this
to do it properly anyway
Im not doing it, and i dont think my guide covers all the knowledge i have on this topic, its just the basic shit. And no i dont wanna do it, i hate this sort of stuff
I didnt ask you to...lol
💀💀💀💀💀💀💀💀💀💀
yo i think this group is struggling
Yes u did @modest estuary
I asked for help not for you to stack the data lmao
hmm so
You guys somehow managed to fix the line artifacts, but now the other problem is dealing with the varying signal...
Now if only there was somehow a way for the stacking software to blend instead of just placing each stack on top of each other..
Stephan, may I have the link to your guide?
mosaicing tools in pix blend quite well
Blending needs to be done manual but idk why youd want that, the artifacts happen if u dont turn of pixelrejection, obviously if the stars differ a lot…thats a problem potentially, also if there is no data in one image and all data in the other…well ya gotta get the proportions right, can just do 1+2+3 and 3xpect it to work, i think i mention looking at the frames and estimating the weight factors if pix cant figure it out right
Is it going well?
Sorry but I lost my stacking knowledge because I never processed in so long
pixinsight?
shitty Siril stack of all broadband data (I got one other persons who uses a tak
) @frigid patrol
ok so
i gotta tune the scaling
this is no scaling btw
better
idk
@haughty iron
halp
@proven chasm
oh and @mighty raptor
sorry for pings
@blazing lake
i cant process
but if you want this stack
ill give it to ya
or the original uncropped one
you can barely see the lines
@late umbra u as well
another crop
I wish I knew how to stack with different lengths 
I'm sorry, but I don't have the expertise to somehow stitch these stacks together
This is really close though
Dunno what you did, but its blending really well!
Literally just threw it into siril lol
I'm just not sure though that much else people have motivation to continue this project though...
I shall
I hate how theres so little info online for this 
I'm happy to continue shooting, I just don't have the time or expertise to stack. Hopefully in the summer I'll have more time so I'll be able to help in stacking too.
so
who wants to process the stack
@late umbra @blazing lake ?
i shall find a way to add the ha
Send it over and I’ll have a look
beware
gradients
and you will need to crop
@haughty iron @night idol @proven chasm (I humbly also request thee to take a look at it)
@frigid patrol ^
didnt really try
the process took 5 min lol
but it has potential
if someone can figure out how to add the ha
I might try later today
idk what i did but on my phone this looks soft
maybe screenshot?
is this better?
thats not full res
oho someones data is fcked
look at them stars
ok
idk whos it is
you need to align them in pix
i dont have pix
so leave the preprocessing to someone that can do it in pix (not me, im done with processing m45, literally spent a month on it this year)
how is the Ha looking
bruh
F
Plus there’s banding 
There’s another ha file but there’s literally no data on it
I stretched it to hell and got no signs of filament
@late umbra
helped
modded dslr?
no clue; best guess is an older dslr
maybe idk
Running NL-Bayes Denoise func
well that F'd up
R channel autostretch
R channel hist stretch
Feel free to process it
Seems pretty dark here, anyone still around? 🕸️
Ye
I uploaded the stack but no one processed it yet
the stack expired
Ill give it a go
when the stack is available
and I need to see its file size as well
I just don't have time nor motivation for astrophotography and discord 
I would love to try continuing this project with yall, but I absolutely suck with trying to combine data lol
Also, my FL is too much to probably do much 
Rip
I also have a problem with focal length...
