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 loading 16-bit Tiffs (287 MB each, from Canon 5dsr) into APP but continue to get this message when I get to registration step. I have lowered the "detect above noise level" as far as it will go. I am not using any calibration frames, just lights.
I have successfully run this type file in APP before.
What do I need to do?
I have the same issue. My question is where is the "detect above noise level" I haven't been able to find it anywhere. The dialogue that comes up is a bit confusing. Most likely my issue is not enough stars since I was imaging during a near full moon and lots of moon glow. I used it before as well on another image with great success. Excellent program.Â

Thank for your time and input.

If it can't detect enough stars, the data must be problematic. 1.077 has a vastly improved star analysis tool that now detects enough stars in tricky data, so this is probably very difficult to begin with in your case. Can you show a sub?
near full moon and lots of moon glow.
Yes, that might interfere so much, that it becomes too difficult to get a reliable detection.
Dear @vincent-mod
I would love to read the answer to the original question since I have the same issue. And I've just tested with the newest version 1.078 but this doesn't work better.
where is the "detect above noise level"
Â
Sure, so that was made absolete by the rewriting of the analysis algorithms. It wouldn't make a difference which is why it was taken out.
OK, thanks for the answer. Then, may I suggest to remove any mention to this parameter? I've got exactly the same error message as shown in the original post with version 1.077
And how about the star size area? was this parameter also removed completely?
Yes that too, should work in almost all cases now if the data is ok, we tested that by looking at many subs which also had problems in different ways before these versions. If you keep having this issue with other data as well, we can have another look for sure.
I notified Mabula about the warning, I never had it so didn't notice that, thanks for pointing out!
