Blown away by this. I used in on my Cone Nebula and it worked perfect. Looks like the latest version of the recomposition has separate "Apply" buttons. So, I guess they fixed it from closing? If it still closes, correct me if I'm wrong, but I'm thinking of a work around. After the Starmask is created, I can bring each photo into GHS make them nonlinear so PS can "See" them. Save each as a 16 bit Tiff and bring them into PS. Once finished in there, bring them back and reconvert into 32 bit for Siril and THEN do a Full Resynthesis to fix star issues and finally do a Recombine? Guess I have something to do tomorrow. lol

I am so excited for these new features. I hate processing stars and these features look like they will solve a lot of my problems. But I am having an issue with my scope with chromatic aberration on my stars. My images don't have the colours aligned correctly and it causes noticeable issues causing colour bleed on the stars where one side will be tinged blue and the other green or reddish dependant on the stars colour. I believe it's caused by a combination of the scope being an achromatic doublett and that I may not have my back spacing dialled in perfectly. I'm trying to resolve the second cause but its never going to be perfect due to the achromatic optics. I shoot in broadband using a Baader moon and skyglow filter. I mainly chose it because I loved the way it kept natural star colour. But I can't really show it off because of the issues I'm having. Do you know if these new features added could fix this? Or is the only way to fix it post shooting going to be to stack the rgb separately to align them correctly?

@DeepSpaceAstro

Жыл бұрын

Not sure how the resynthesis would handle it. They say the star colors won't be lost, but maybe the synthetic stars will have less of the tinged colors. Give it a shot. It runs relatively quickly. Then blend them back in with the recomposition tool. Maybe keep the star mask stretch light will help as well.

Hey Rich. Howzit? ONLY since recently, Siril became very picky with stacking frames. I had many images as the one you showed in the vid, however since I reloaded 1.2 beta it will not stack frames that have even only slightly elongated stars. So a question, how do you get an image with "badly elongated stars"?? I know, I should do manual stacking, but I only recently moved from piles of mussel shells to the abacus, and one of the upsides of Siril is it has automated script.

What about avoiding elongated stars during acquisition? By the way, Blur XT does this automatically, even if elongated stars only in corners.

@DeepSpaceAstro

10 ай бұрын

Sure, avoiding that or reshooting the image will always be the best solution, and I mentioned that briefly in the video. This is just a way to correct the stars if you can't reshoot, like if you went to a dark site hours away, and didn't realize the stars were elongated. You can fix them since chances are you wouldn't head back out to that site again to reshoot. And yes BlurXterminator can do this, but that's only for PixInsight.

I followed these steps for the saturated stars (ie, not script, just menu) and with D-PSF I got one maroon star. I next ran Desaturate Stars but the maroon stayed even after clearing D-PSF tool, then re-selecting, getting maroon again, and even running Desaturate again. On a zoom, I can see the star changing shape on each iteration. Is that just a seriously sick star, keep iterating?

Oddest thing, I was (admittedly rushing) to process an NGC6888. Stacked image (r_pp_*stacked.fit) and when I ran Resynthesize all, the whole nebula disappeared. I've used Resynthesize before on images pre-Starnet removal (I think!)... did I do something stupid, skip a step or something? Reason I was doing this was same logic as Deconvolution... reshape before Starnet to avoid artifacts around the stars if I were to reshape them after Starnet and then not have a good fit when the stars come back in.

Well. I will have to test it more but this function removes elongated stars by replacing them with fitting round drawings of stars. That alone seems a bit questionable, but it also heavily depends on the correct star recognition. And it often recognizes doubles as one star, killing your data. For me, this is not the way. I like pretty pictures but the stars should be correct.
