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.
Hello,
Even with integration of 20 lights APP has been freezing the desktop needing hard reboot.
Tried suggestions on forum and reduced allocated memory to 16GB, turned off openGL4 and reduced threads to 10 out of 16 available.
The reduced threads helped with the smaller integrations and openGL4 didn't matter.
When trying integration of 54 lights in 4 sessions using MF, MDF, MD and MB it hangs again!
Desktop specs - windows 10 with intel i7/32GB Ram/Nvidia GTX 1650/SSD 1TB
Any help is appreciated 🙂
Interesting, what version of APP are you using?
@vincent-mod APP version 1.083-beta3. Reduced the threads to 6/16 and ran again with same data set and it worked.
The stable release of 1.083 is also available now, some errors have been solved in that as well. You can find the link on top of the forum.
@vincent-mod Even the stable release froze the computer. Retried with 6/16 threads and it worked fine.
Mmm, quite strange and it makes me think there might also be an issue on your system specifically. I tend to up my threads to all I have -1 and my memory use to 30 out of the 32 GB I have. Never froze here, is there some other software you might have that really stresses your system just to check the system itself?
@vincent-mod TeamViewer & google drive were running. Stopping TV didn't help!
@vincent-mod Solved! The problem was due to Google drive. All files loaded into APP were in Google drive folders with offline access enabled. However, GD ran into errors when APP used 15/16 threads. Copied the files locally and everything executed smoothly with default settings in APP.
This error came to light when examining Event Viewer on the desktop.
Thanks.
That is a great find! I wouldn't have guessed that. 🙂 It's indeed always better to process data locally on preferably an internal SSD. Was GD still syncing in between maybe?
