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 was trying to process a session with 360 lights, 120 darks, 120 bias and 120 flats on my windows 10 machine with 32GB ram. The processing would randomly just stop without any error message. I could drag around the windows, the UI would still render fine. But everything seemed stopped. Finally after hours I decided to kill the openJDK process. This happened every time i tried since then. But it stops at different points in the workflow. At one point I just tried the 360 lights, and master dark, bias and flats. It managed to produce the integrated fit, but it was stuck after that. I had to kill the process. Any idea what could be happening ? Am i hitting an upper limit of files it can handle at one go?
It never seemed to use more than 4-5GB RAM.Â
rebooted machine just to be sure and tried again. happened again at 84% of integration after 6-7 hours of processing. time to try something else.
Hi @app3sashimi,
With wich APP version does this occur? With the latest 2.0.0-beta20? If so, we are working on a stability issue at the moment, so that might be your problem as well. I think I have a solution as well and I am working to fix it a.s.a.p.
Edit: If you are using Windows, can you try this version:
and let us know if this fixed your issue?

Thanks Mabula, kicked the process off. will report tomorrow.
Mabula fixes worked! Thank you.Â
