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.
version 1.082 - What should I expect. I have designated 36 of 40 megs of ram in my 2019 iMac to APP. It is using 5 of 6 threads. Frequently I see the app is showing only 1% of use with occasional jumps to 70 or 80%. The files are on my local harddrive desktop.Â
I am now approaching 8 hours of processing (my second effort at this because I thought something was wrong the first time and so quit and rebooted and restarted. Â
I am try to process 300 lights and the MF, MD, MDF, MB, and BPM. now after these 8 hours I am still at just 52% of integration. Â
None of my earlier projects took near this long. Â
Is there anything I can do? For most of the 8 hours the computer was not in use. Now it has only been in use to to examine the progress and send this message. During this message, the APP has only reported the use of 1%. Maybe I don't understand what that means, but it seems there must be something I can do. At least in the future.
Thanks for your help.

Is your Mac going to sleep or activating a screensaver in between? I've noticed this to be an issue on MacOS sometimes where APP stalls if that is active. I hope these kind of things get solved when we are on Java 11 which is our direction right after the next update.
Apart from that, processing does take time as it's using more complex algorithms than some other applications. The reason though is that it does enable us to produce better results more easily. It's a trade-off in that sense. We are always improving steps for speed and GPU processing will be a thing in a future version as well.
Thanks for your reply. I will check on that.
