Curious to see what people come up with!
#North America Nebula - SHO - 11 hours total

What scope is this? Those are some tight stars!
I ended up cropping it quite a bit, there was a bit of a gradient on the channels that made the edge signals kinda weak and I really had no desire to share weak, uninteresting data lol
Also, worked pretty hard to bring out some of the clarity in the wall itself. It should look pretty good if you open it full screen.
I need to learn range masking a little better though, I would have preferred to convolute some of the clouds floating among the lake of Oiii

It's a redcat 71. Strange that you found a gradient, though, as the RC hardly vignettes at all, and these are narrowband. There is certainly less data at the edges because it is just empty space though.
Either way looks pretty good! Thanks for working with it hope you enjoyed!
slim void
I did. I'm probably picking up a redcat at some point. I also found it kinda wierd as well, I probably could have gone ham with background extraction and removed it, but just felt lazy. 2600/268 always has such a clean image, mine always come out completely flat, so I was surprised with yours. It wasn't huge tho, I could have worked with it.
If you want, try my Soul data in this group as well. 🙂 It's pretty clean.
winged cypress
Hmm, wondering what steps brought you there. The top image is that same data and I did nothing for DBE once I combined the channels
Now you've got me curious, haha. opens PI but should be working
slim void
One sec, I'll see if I can show ya. I thought it was the sulphur channel, but that's clean
I think it was the Ha channel, I'm starnetting it atm, hard to tell without. It's subtle
Here it is on the Ha. Dim stuff on the left side is weak
Might be moon glow? Not sure tbh. Usually Ha is the strongest.
winged cypress
If I see moon anywhere it's in Oiii usually
Did you stretch that manually or is that STF?
slim void
that's just STF
winged cypress
Idk, that's weird. I'm in B5 so its obviously not going to be pure darkness but I'm just wondering if STF is pulling too hard there
slim void
It's still a linear image, STF isn't going to pull harder on one area than another. That's where curves come into play.
I think its just a dim area.
winged cypress
Yes, I didn't mean it was literally grabbing a dim area and stretching it further 😄
slim void
The sulfur is hot as hell. I guess its still somewhat present but not nearly as noticable
winged cypress
My Ha doesn't have nearly the same glow you are showing with an STF
That's what is confusing me
It just looks like signal to me
slim void
Is that DBE or ABE?
winged cypress
I haven't done anything this is the same data I uploaded
slim void
If I don't ABE it, it's less 'gradiented' for lack of better words
slim void
Maybe I'm just too used to my light bucket. I've never seen it before.
slim void
I dont remember if I actually may have skipped BE for that reason...
but I do know I noticed it
so I just said screw it, I'm gonna crop it lol
winged cypress
😄
slim void
background extraction on my data hardly changes anything. I love these cameras.
winged cypress
Well, background extraction also relies on having background reference. The nebula covers almost the entire frame here so it's pretty much impossible to get an accurate DBE. If there even WERE a gradient, you'd probably do more harm than good running ABE/DBE
You'd really need to manually specify points in the blackest areas.
I'm just glad I didn't stupidly upload the wrong files 😄
Gonna play with your Soul (lol) after work
slim void
lol that's probably why I didnt do it. I really dont remember, it was 4am
slim void
Gonna play with your Soul (lol) after work
kek. I think you'll enjoy it. I haven't done flats yet for my narrowband, and I'm not sure if I need to. They're clean, but theres always a tad of skyglow in my backgrounds.

I really like how dark the dust came out. Very nice data!
