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.
Just reporting that I just had my first full Windows crash and reboot (no blue screen even!) using APP for as long as I can remember.
I was doing a quick integration and HaRGB combination and had saved the raw combined FITS - then I went to save the stretched version as well (something I normally do) and the system froze before rebooting - no file save window appeared and not even a blue screen so no message or dump file. I checked to see if there was a new version and updated just prior to doing the sub calibration/combination
I was doing some data analysis for work earlier so APP wasn't the only program open but this workstation isn't short of system resources. I didn't touch the 47 out of 48 threads - I'll drop that back a bit in case it caused Windows to choke. I have to get back to some work so I can't repeat the process for the moment but will take another look later.
These are the workstation specs. Windows 10 (build 19044), Threadripper 3960X, 128GB RAM (not ECC), Quadro GV100 GPU
Best regards

Thanks for sharing, this does sound like a system issue possibly, which can happen sometimes. What version of APP are you using right now?
@vincent-mod
the latest beta release. It’s just a little odd as it’s a long time since I had any system crash that bypassed the blue screen. Cosmic ray perhaps? 😂
Ha! Well you never know. 🙂 If it happens more often, please post here and we can maybe have a closer look.
