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 1.083.2 release notes, this is a quick release after the stable release to fix a couple of issues that were reported on 1.083.
- FIXED, CONCURRENCY ISSUE IN CALIBRATION ENGINE, as mentioned in this topic https://www.astropixelprocessor.com/community/postid/21090/ the calibration engine was not behaving properly. It could not find masterdarkflats for flat calibration in this case allthough they were provided. It was a concurrency issue which will occur if more than 1 master is created in MasterBias, MasterDark, MasterDarkFlat, MasterFlat creation.
- FIXED, REGISTRATION, if registration fails on 1 or more frame the actual count of successfully registered frames was not correct.
- IMPROVED, FITS HEADER, APP will now read and use the following fits tags as used by MaximDL, BAYERPAT = VALID and XBAYROFF & YBAYROFF to interpret the correct Bayer Pattern for Bayer data.
- IMPROVED, FITS HEADER, APP will now use the GAINRAW tag to find the GAIN for images shot with TheSKy.
- FIXED, STAR REDUCER TOOL, if a too high kappa was set for the noise threshold, the tool could produce a Null Pointer Exception, because no stars were found... This can happen quickly when non-linear data is loaded into the tool. Now this exception is caught and the tool indicates that you need to lower the thresholds...
- IMPROVED, RGB COMBINE TOOL, I have added 2 more preset formula for the famous Hubble Palette or SHO composite. You now have SHO1, SHO2, a new SHO3 and a new SHO4.
