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.
Ok, so first image in a while, also its a first with the new 1.077 version, its come out ok but still seems to be left over lp even after running lp removal 4 or 5 times, also looks grainy, is there any noise reduction settings I've missed?
Theres about 6 hours per filter integration, and the fit file was too big to upload, this is a 10mb jpeg and looks worse than it was in fit.

The problem seems that the light pollution either isn't actual light pollution, or it created a weird pattern maybe due to internal reflections? It should normally be a gradient, which means it's gradual and not this spotty. You can see that I tried to make a correction model on the jpeg above (not ideal to do like that but ok) and it's not a normal gradient, which makes it pretty hard to correct.

🤔 Wierd, it doesn't show as much on the tiff (I said fit above and I meant tiff)
@vincent-mod
ok so this is as good as i could get to best show it, its a screenshot of the 45mb tiff, I like the star colours, they've come out better than expected but what you cant see is the grainyness.

I always over-stretch and over-saturate to better see the issue in the background. And then I place my boxes, does help a lot. The grainyness will likely be left over because of the uneven background and maybe not enough data, getting that better usually requires darkers skies and more data.
