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-beta3 release notes
- FIXED macOS support: APP should now run again on older macOS versions before Big Sur 11.0. Minimum required macOS version is now macOS Sierra 10.12.6.
- FIXED macOS LibRaw: libraw was not working correctly in beta1 and beta2 giving crashes when RAW frames were loaded. This is now fixed on Intel and M1/ARM hardware.
- FIXED SAVE TO FITS: with non-ASCII character in reference file name like a degree sign is now fixed.
- FIXED conversion to 32bits Integers:if you would save in 32bits Integer FITS files, the conversion to 32bits integers was not correct if you would convert from 32bits floats or 8bits integers. Both conversions are fixed. The conversion from 16bits integers to 32bits integers was already working correctly.
- FIXED LICENSE INFO: sometimes the computer ID was not found when you check your license with the LICENSE button.
- IMPROVED number of CPU Threads to use: the setting on the top left for number of CPU Threads to use will now be remembered between restarts of APP.
- IMPROVED application header and LICENSE button information: both the application header and the information as shown with the LICENSE button regarding the APP version, now shows the hardware architecture of the machine on which APP was built. This is very usefull for macOS users that install an intel or arm/M1 build on their mac computers. The layout of the information as shown with the LICENSE button is also fixed for string lengths now.
- FIXED Out Of Memory warning : we have fixed this warning when APP runs out of memory. The old pre-2.0 APP versions, allowed you the option to adjust RAM amount with the CFG menu. This is no longer possible, so we removed that part of the warning.
