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.
Astro Pixel Processor 2.0.0-beta6 release notes
- IMPROVED BLACK DATA CLIPPING WARNING from Calibration Engine
We realize that this warning caused some frustration allthough we do think that it is an important warning still to make the user better aware of data issues leading to possible suboptimal results. To remove frustration about the warning, we have increased the threshold for the warning to appear. Furthermore, the warning will only show now after a long running task completes. It will not stop a long running task anymore. The warning will not show at all if the calibration warnings are turned of in 2) CALIBRATE.
- FIXED AND IMPROVED WINDOWS INSTALLER
The APP icon when the application is running now properly shows on windows 10, 11. Also the icon is shown properly in the windows remove/uninstall list. The application can be pinned to the taskbar from the start meny icon. When the installer is started, the user is shown the choice to install APP for all users or only for the current user. Installing for all users requires admin rights and allows you to install APP in c:/program files/astropixelprocessor now. Further confirmation is needed but this might fix issues with the file chooser on windows 11 as reported by some users.
- FIXED and IMPROVED Bayer/X-Trans Drizzle data normalizationÂ
As reported in this topic https://www.astropixelprocessor.com/community/main-forum/drizzle-and-dual-band-filters/ there was a bug in Bayer Drizzle processing, especially with O3 data. It turned out that Bayer Drizzle had 2 bugs. The first bug was that data normalization was not working correctly. This is now fixed.

- FIXED and IMPROVED Bayer/X-Trans Drizzle HaO3 extract O3 & HaO3 mono narrowband processing
As reported in this topic https://www.astropixelprocessor.com/community/main-forum/drizzle-and-dual-band-filters/ there was a bug in Bayer Drizzle processing, especially with O3 data. It turned out that Bayer Drizzle had 2 bugs. The second bug was that the O3 data reconstruction from the green and blue channel was not working correctly. This is now fixed by properly scaling the O3 signal in the green and blue channels for O3 extract and similarly for HaO3 mono reconstruction. This fix has a strong positive effect on the Signal To Noise Ration of the results 🙂 :
- Added possibility to detach the console to a separate window and save its location and dimensions
This brings back the detached console window for those who liked having it, as well as making it useful for multiple screen setups.
