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.
I installed APP 1.075 on my linux box, opened an old jpg image of m3 I once took. Attempted to run light pollution tool on it. Trying to "Show Corrected Image" threw an exception, a strange swingy one:
Encountered error in module:
CreateLightPollutionModelAndShowResultTask
Error message:
java.lang.ClassCastException: javax.swing.plaf.nimbus.TextAreaPainter cannot be cast to java.awt.Insets
Cause:
javax.swing.plaf.nimbus.TextAreaPainter cannot be cast to java.awt.Insets

Is this a consistent bug popping up?
Hi Shlomi,
What Linux distribution are you running? I am on Ubuntu 18.04 with no problems.
My laptop is 2 years old, purchased from System 76.
Â
@oopfan I also have a System76 machine (unfortunately, I really don't like their machines!), but with 16.04.
@vincent-mod No, it is not consistent.. Actually, I just tried to reproduce it but couldn't.. However, since the exception is of a "Casting" type on Swing components (the UI), it does not look like its data oriented (depending on the images being processed), so I suspect it still lurks out there. Unfortunately, the short stack trace snippet that was shown in the error window does not give anything into APP code..
If I can reproduce it I will dump the entire log in here.
Thanks!
