Re: M42, with issues...

Wondering if you came across this one? https://www.astrobin.com/forum/c/astrophotography/deep-sky/horrible-vignetting-with-asi6200-and-at130edt/ Now that's a full frame camera, but still kind of similar. And his circle artifact does "fit" a little better across his sensor. They float a few theories,...

Re: Astro to Astro-art Continuum, 2024 Edition

Hi Dietmar, thanks for adding your perspective. :thumbsup: I agree with a number of your takes. I would like to see just how they enhance the images, nuts-and-bolts description. And yeah, are they using the same FITS Liberator that I have? Mine is so limited it almost seems worthless, other than rea...

Re: LRGB or RGB?

First little experiment (partially) complete. :? I have yet to dive deeper into my archives, but the data in front of me right now followed my usual OCD pattern of acquisition -- mostly equal total exposure each for L, RGB, and Ha. Ditto on the second night. That makes it easy to run off some compar...

Re: M81/M82

Oh. Cough cough. I think you are right. :shock: Granted I am an aficionado of dark backgrounds, but even beyond that I think edit #1 is the clear winner, though yes H-IX pops more in edit #2. I guess more faint stars are showing too, and I like that, but ouch that bright purple sky. And the main tar...

LRGB or RGB?

So there's been rather lengthy discussion over on CN-EDSI as to whether it is better to spend time taking L, or to devote that same time gathering more of RGB instead. I think this would interesting to those of us doing mono. As the whole thread now spans almost 30 pages, I haven't been able to foll...

Re: Astro to Astro-art Continuum, 2024 Edition

Due to another discussion about NB palette options, I was doing some googling and came across this article that summarizes steps taken by the pros who process JWST data. https://webbtelescope.org/contents/articles/how-are-webbs-full-color-images-made They also mention it's very similar to what is/wa...

Re: M81/M82

Everything seems quite clean. :D Plenty of integration, so it should, though I imagine the F7 requires it also. With so much Ha, I imagine you could go stronger (or redder?) than the light touch you used here. But, matter of taste and it can easily overwhelm. M82 looks sharp. I went back to check my...

Re: NGC 3324 Gabriela Mistral Nebula

Hi Martin, After 1.9, going back to 1.8 is similarly SLOW! :lol: Would be interesting to hear your takes on it though. SVD has been changed up a fair bit, and there's been some relief to the creation of flat white disks for coalesced star cores, which I found troubling myself. But there's a lot goin...

Re: NGC 3324 Gabriela Mistral Nebula

Beautiful shot, Martin! :bow-yellow: And the retro 1.7 processing looks great too. Seems you may be revisiting all your greatest duoband/OSC hits, now in SHO/mono and I suppose the CF Newt as well? The third channel - if there's data to be found - really does add the touch that takes the overall ima...

Re: M42, with issues...

All things considered, I'd call that an admirable 4-hour Orion. :) Perhaps a wee tint of green in the blue stars, and overall could maybe use a little more acutance. ;) On the right side, in deep images there actually is stuff over there. In fact there are two in EDSI right now - Dance and Yuexiao. ...
