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.
It would be great if there was a default box size that would be drawn in tools that require it with just a click. That way, instead of having to manually draw lots of small (and inevitably differently sized) boxes in those tools, a click would just give us a default size box. A click and drag would still draw a custom size box. That would save a ton of time processing images with complex light pollution etc ....
Hi @heylers,
Thank you very much for your request. It is however now something that I want to do, because the size of the area select box matters a lot on the actual correction that you will get. Small boxes will produce less good models than big boxes 😉 If there is space, better to draw a big box instead of a small box. Furthermore, placing many small boxes is not the best way to correct any image allthough some videos online would claim otherwise. Finally, best correction will be achieved with an iterative process where you place just 5-6 boxes to start with, click calculate, and then between each calculate afterwards only place 1-2 new boxes, possible remove bad boxes if they turn red and you are not sure if they are placed well. Many images even with complex light pollution can then be corrected with only 20-30 boxes.
If illumination artefacts exist, then only place small boxes on both sides of the artefact to solve it.

Ah. This is why we need that printed manual!
if there’s no “most common” size box, then nevermind 🙂
