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-beta30 release notes
- UPDATED DEVELOPMENT PLATFORM to Oracle GraalVM 23.0.1
We have updated the development platform from GraalVM 21.0.2. to 23.0.1. This should solve stability issues on the latest operating systems like on Windows 11 where some users reported instability.
- UPDATED JavaFX to 23.0.1
Needed for the support of the native File Chooser dialogs. The File Choosers are the same as in beta29.
- UPDATED FITS support
We have updated the 3rd party library for READ/WRITE FITS support to nom.tam.fits 1.20.2
- IMPROVED Analytical Chart with annotation of the reference frame and image viewer frame
The analytical charts of the dataset will now clearly show which frame is the reference frame (REF) for registration and normalization. It will also show which frame is currently loaded into the image viewer with the new mark VIEW. The VIEW mark will also be shown in the frame list now.

- IMPROVED Analytical Chart, double clicking on a point in the graph
will load that image directly into the image viewer with the current image viewer mode (raw/calibrated/registered/normalized/starmap)
- FIXED fast startup for computers with little amount of cpu cores
As reported in this topic https://www.astropixelprocessor.com/community/windows/problem-starting-program/#post-30162 the new fast startup of Astro Pixel Processor was sometimes not working well on computers with only 2 or 4 cpu threads. This is fixed and it will still work with only 1 cpu thread in the system.
- FIXED histogram zoom disabled
It was possible to mouse click on the image histogram and lasso part of the histogram to zoom in. This is no longer possible because it does not really serve a purpose, only creates a weird graph.
