2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster đŸ™‚
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
@mabula-admin Nice to read you Mabula and to be able to enjoy this beta 30 version.
My thoughts also go out to Vincent and his family, we can only wish him a speedy recovery and thank him for all he has done for APP. We can't wait for you to be back in shape to continue your contribution to this excellent astrophotography software.
I'm also one of APP's first users, and I've always believed that this application makes a difference. I still use it with great satisfaction and pleasure. What some people don't understand is that you're a perfectionist, Mabula, and you'd never release a version of APP that you weren't completely satisfied with... That's what makes you and APP such a great value.Â
Wish Mabula, Vincent and family, and APP all the best!

Dear @mabula-admin,
I'm glad to see updates flowing in regularly, as was the case before. I'm quite happy with the product.
It's so easy to complain... so please accept my congrats about the great work.
Best regards,
Rodolphe
Hi Rodolphe @rodolgo,
Thank you very much for sharing your feedback! It is our pleasure and we are also happy đŸ™‚ with the current situation. We aim to go further like this and give APP a great future.
Mabula
@vincent-mod Good luck & best wishes Vincent!
Thanks Timothy! All is still looking good fortunately. đŸ™‚
The auto-stretch function "Auto Under" overexposes bright highlights significantly. Can fix?"
Hi Dave @rustyd100,
Thank you very much for your question. Can you show a screenshot perhaps if what you are seeing? Without some visual guidance it is hard to understand what you are referring to. You can attach a normal screenshot in jpg or png without any problem.
Thanks,
Mabula
Hi @mabula-admin I saw last time new scripts on the social media called veralux and there was another new one, idk the name. It's for PI and siril.
But is this possible in your Astropixelprocessor?Â
Dear Stefan @stefanastro,Â
I have also seen that on Facebook for Siril. If you can refer me to the Veralux source, I will have a good look đŸ˜‰
After the 2.0.0 release we will soon work on better image stretching for sure.
Mabula
Hi Stefan @stefanastro,
Thank you very much. I have added this to my todo list to work on better stretching in APP after the upcoming 2.0 release đŸ˜‰
I need to make it more intuitive, color preserving and much faster for sure đŸ˜‰ so I will do major work on this after 2.0 for sure.
Mabula
So sad to hear about this @mabula, maybe you should hire another developer to help you out. Â
I like the Adaptive Deep Sky Stretch panel's simplicity compared to the former viewing panel. However, it would be very helpful if my ADSS slider settings could be retained when APP is shutdown. I find that I have to greatly decrease the Color Preservation slider every time or else my image is greatly oversaturated. Thanks and my best wishes for your health.
Hi Joseph @jb-niemeyergmail-com,
Great, of course, I have added it to my todo list to save/load the ADSS settings per APP restart.
