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 🙂
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.
After having loaded files, any attempt to set a save directory sets that save directory to the last load directory used. For me, this behavior originated after an update from beta 41 to 45 in windows11.
The available workarounds are to set the save directories before loading any files or not attempt to set a save directory and allow files to be saved to the Work directory.
Dear Steve @stevejteel,Â
Thank you. very much for reporting this, indeed, I just tested this and you are right. I will fix this as soon as possible and will release a fixed version.

Very much appreciated
Hi Steve @stevejteel,
Thank you again for reporting this issue in beta45. I have found the issue and have fixed it for the beta46 release:
- FIXED Set Save Directory
2.0.0-Beta45 had a regression bug where setting the Save Directory did not work as expected. This has been fixed. It was reported here: https://www.astropixelprocessor.com/community/windows/problem-setting-save-directory-in-app-2-0-0-beta-45/#post-34703

@stevejteel, 2.0.0-beta46 was released today and has the fix for the Set Save Directory 😉Â
