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've never ran into this issue with any previous version (tested on APP 1.083-beta2)
, but i keep having issues with app doing this no matter what boxes or areas i select.. anyone else ran into this one?

Thanks in advance
edit: ok, i dont think this is beta related, i dropped back a version, same issue. The image is originally an Lenhance image with the asi294mc pro. Calibrate background has the same effect
Here is the Lenhance original image that was integrated:
That's a weird one indeed. So when exactly do you get the result on top?

Its with the light pollution removal tool and also with the background tool
Mmm, what happens if you do this on an integration where you didn't use calibration data?

Really strange, so if i take out the masters, it is a reddish image, but if i enter the light pollution tool, it neutralizes things and aside from the need for a dark, its strangely normal looking already without a flat (maybe some biproduct of the lenhance, unsure, though i know there are spots that should show up).
At any rate, if i make squares and hit calculate, nothing much happens that i can see visually, though it doesnt break and get inverted in this scenario.
Ok, that does point to an issue with the calibration data I think. If you want I can have a look at your masters.
