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.
EDIT by Mabula: bug was fixed in 2.0.0-beta29 !
I am trying out APP but I am getting an error popup when calibrating masterflat. See error below:
Encountered error in module:
LightFrameCalibrationError message:
java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1Cause:

The process just stalls and I can't do anything but close the program.
I am using Arch and APP 2.0.0-Beta26
Hi Nils @nilz,
Thank you very much for posting your issue.
Can you share more information on the data that you are trying to process?
Is it monochrome or OSC/color data for instance? Have you changed certain settings in 0) RAW/FITS?

Thank you for your reply. I am using OSC shot from a DSLR, with settings in 0) RAW set to RGGB pattern and Adaptive Airy Disc with use camera white balance and use camera color matrix enabled. Anything I should try to change?
Hi Nils @nilz,
With DSLR, there should be no need to set the Bayer pattern in 0) Raw/Fits, because it will be detected automaticailly. But, setting it yourself should still work of course, so something is not right.
Are all the files, the lights and calirbation data from the same source? I mean from the same capture software or hardware? Are you loading the DSLR raws or perhaps converted FITS from the capture software/hardware?
Mabula
I was loading only DSLR raws. I tried changing the pattern to supported and enable "force bayer/X-Trans CFA" and now it seems to work fine, thank you!Â
