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,
I have a question regarding point 2) calibration.
I'm currently experimenting with darks, different temperatures, with / without scale, different numbers, etc., and every time I load new / different dark files under 1) and delete the previous MasterDark.
If I now click on Intigrate at 6), APP doesn't start with 2) Kalibraition but with 3) Analysis Stars, I always have to create the MasterDarks myself and then choose Integration.
Is that wanted or does APP not notice that I have changed something in the calibration pictures?
thank you
Hi, my personal experience is that if your subs have calibration data ascribed to them from a previous calibration (as yours will) APP will go straight to Analyse Stars. You will have to force a recal once your revised calibration files are loaded. Hope this helps. Good luck with your trial.

Try clicking "(Re-)assign Master to Lights" in the 2) CALIBRATE tab first.
@ ChrisPeace and RalphSnel,
I delete the master files under 1) Load and also delete the assignment under 2) Calibrate but APP still starts with Star Analysis.
Have already tried to have the master files calculated and smelled at 1-2% and then under 6) to have everything done automatically, but that doesn't work either. So I have to start the new master file calculation by hand and I can then run the rest at 6) automatishc.
A bit cumbersome but I guess Mabula did not think about the programming of experimenters like me 😉
Since I have a DSLR without cooling, I wanted to know how much different temperatures of the darks have an effect ... so with the calibration function (?) Of the master files there is hardly any visual difference. I have no idea if my experiments are so meaningful.
