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 am following the tutorial but I am getting anerror message when registrating. Any ideas what causes this?

Were you able to select the comet etc?
@vincent-mod
Yes. Then the comet position was dtected in each frame and then the error occured.
Strange...
I closed APP and tried it again with exactly the same settings. Now it worked. 🤔Â
Interesting, maybe a very specific glitch. A new version will be released soon and it will be more robust by then as well.
Hi @vincent-mod,
I have a large set of very short exposures that cannot be aligned with APP currently, as they contain less than 10 stars per sub and a bright core of a planetary nebula. I wanted to use the comet registration feature to align those cores to get around this problem and ran into the same error message after selecting the comet:
I also remember getting the same error message last week in another case - but I guess I cannot reproduce that one for you again. Has the cause of this problem been identified and will it be addressed in the next beta and do you have any idea, when to expect the second beta?
Best,
Phillip
This is not possible yet with the comet registration. There are some good improvements for star detection though in the upcoming beta, due to the work on comet registration and star reduction, Mabula managed to get that improved as well. So, we have to wait for that release and then try again I think.

I was getting this error message. Switched from OpenGL to CPU, and it seems to have gone away... I'm on an M1 MacBook Air.
I have experienced a bit different error in 1.083-beta2:

Yes it's not perfect indeed in this beta yet. Mabula is improving it and the new release will have some improvements here as well.
Hello, I also registered today and downloaded the 30-day free trial version 1.082 and upgraded to version 1.083-beta2. I encountered an error in my first comet operation. It's a sad situation!
