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.
First the performance of the new version is amazing. I recently got a 24-core Threadripper 3 computer and combined with the performance improvement of V 2 means processing hundreds of subs no longer requires overnight processing.
Now a problem is carrying over from the old version, I do a lot of bi-color processing with my OSC camera and L-Extreme filter and then using the Ha and O3 extracts. If I attempt RGB combine with the files straight out of Integration, everything runs fine. However, if I preprocess with Light Pollution Removal or Cropping, the resulting files are converted from Grayscale to RGB and won't combine as expected using HOO1 or HOO2. It takes multiple clicks to load each file. Is there a way to keep the extracts as Grayscale through these preprocessing steps?

Hi! I know you're busy with the new release but still want to find out about this - why doing crops or lpc on a Ha or O3 extract from OSC changes the extract from Grayscale to RGB.
Thanks!

Sorry, must have missed your post. I don't think this should be the case, I'll forward it to Mabula.
Ah, I see we did add your issue to our issue-list to be solved, this is going to be tackled indeed.
Closing this issue, has been solved already in the past...
