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.

Hi Mabula,Â
I've got a small problem with the latest version (1.065) when i create a large stack (around 280 files in the range of 31 mb) APP will crash when it is doing the LNC. Can you tell me if it is a small problem in APP or it is a problem with my computer?
Â
Kind regards,Â
Jan-Willem
Hi Mabula,
I just tryed als the APP version 1.063, it have the same problem.Â
The problem only occours when i did something else like registering and save files. When i do something like that i always press the CLEAR MEMORY button and than start over wih the new task.
I did shut down (only APP) complete, start over again than it seems to work again.
Â
Cheers Jan-Willem
Hi Jan-Willem @jw_duijndamhetnet-nl,
Apologies for the late reponse on your problem.
How are things working in APP 1.068? I did alter quite a few settings memory wise in the latest versions and I think the current settings are better.

Hi Mabula,
It did happen yesterday agian, i would make a stack of around 190 frame's (30mb each) and the same error occured.
Before this error i was making star color calibrations on 3 differend images, between every image i did clear the memory (strange to see that every time the used memory went up, when i star it was arround 140mb, second clear app. 500, third app. 1200 so the memory is'nd clear all the way), after that i did load 60 flat, 1 bpm, 1 MBias, and app. 190 light frames. I agian blow out on the LNC correction 2e itteration.
When i did close APP complete, start up again (also the memory is than app. 140mb) than did run the stack again it worked.
I hope this is helpfull.
Â
Cheers Jan-Willem
