I've stated many times; what do astro-photographers do on cloudy nights? They reprocess their images.
I have a set of data on M31 that dates back to 2017 (taken with the RASA11) and at the time with my 60Da DSLR. I reprocessed it in 2020 when I was getting more experienced on PixInsight. I then dusted off the data again in December 2024 and reprocessed it with some of the new skills I've learned during this passed year including BlurXterminator.
I've attached all three images; keep in mind the data loss due to the reduction in jpeg file size. Zooming in definitely shows the improvement over the years. Let me know your thoughts on where the improvements have been the greatest.
Thanks
Barry
Beautiful improvement, Barry,
Phil

Barry, you can see significant improvements in each image and of course the last image is the most improved. On Monday, February 3, 2025 at 04:28:15 AM EST, BARRY YOMTOV via Photo photo@lists.gaac.us wrote:

Hi Barry, clearly the detail is improved on the latest iteration. Blux
makes a difference.
I have to say though I thought the color balance was best in the middle
frame, a minor matter

Guys, enlighten me, because I have a 32" 3840x2160 pixels IPS monitor and I don't see any improvement in the last image, except maybe a little bit more 'bluish' clouds on the perephery of the galaxy.
No additional stars; not meaningful change of colors; and less contrast, making the last image less pleasant actually.
I like a lot that image, bravo, thank you for sharing, detailed, nice colors... But I don't see any improvement with the additional processing.

Well, I will leave it for Barry really, but.. zoom in and the shock waves
are tighter, and more distinct.
Join the next photo group meeting maybe Barry can demonstrate
