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 1.041
- Fixed, in regstration of frames, sometime a null pointer exception pops-up from the Find Best Registration Hypothesis module. This message popped-up because several exceptions weren't properly handled. The errors had no impact though on the registration result, but were rather annoying.
- Fixed, error in new preview filter slider panel, gave error on EDT drawing due to not setting GUI change on EDT thread.
- Fixed, calculation of needed HDD space for light frame integration task wasn't correct when Multi-Band Blending was used.
- Added, console panel with output of processes is now added.
- Fixed, during a "big" multiple view calculation, the GUI could freeze due to an error in one of the algebra modules.
- Improvement, speed of Hessian creation in Trust Region Levenberg Marquardt algorithms has been increased.
- Improvement, upgraded to latest version of EJML Matrix library.
- Improvement, multiple view algorithms now support 10000 stars in the multiple view solution (used to be 6000), so mosaic solutions should be more robust now.
- Fixed, GUI imageviewer, while scrolling in the imageviewer, sometimes the gui froze while scrolling due to drawing of a new histogram while scrolling.
- SPEED Increase and Fixed, light integration with outlier rejection was slow due to inefficient array creation. This improvement/fix should really help with integration of big stacks.
- Fixed, while running a preview filter, the tooltips (if enabled in the CFG menu) will be temporarily disabled. Other wise the tooltips can be a bit annoying while using the preview filter.
