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'm currently using the trial version before deciding if I should purchase. Â I'm running on a Mac running Catalina 10.15.5. Â I have a couple of things that are really annoying and wanted to get some feedback.
1.) Every time I start the app I have to navigate to my working folder. Â As I created my 'base' working folder on another partition, I have to constantly navigate all the back to /Volumes and then down from there. Â Why can I not select a base working folder that is saved and used on app launch, so I only have to then navigate down to my working folder (i.e. based on object).
2.) I use the Apple Mouse with touch scroll, however the scrolling in the windows is way too sensitive and I keep going back and forth, for example when zooming into an image or scrolling left/right in the list of frames at the bottom.
3.) Say I want to scroll on star density to select which images to keep and which to reject, I have to scroll all the way over to 'star density', then all the way back to deselect. Â I can move the 'star density' column over next to the select boxes, however as soon as I deselect something, the 'star density' column jumps back to it's original position. Â This is really frustrating.
Thanks,

Hi Adrian,
I have been using APP on MacOS for over 1,5 years now.
1) This has been requested many times and @mabula-admin has it on his todo list with other configuration items to make permanent.
2) I have noticed this as well. It takes some practice but if you carefully use the touch pad then it is possible to scroll more slowly.
3) I never tried this so no clue.

HTH, Wouter
