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.
Another small quality of life improvement during calibration - if I make a change and re-do calibration, I may get the pop-up dialog box asking me if I want to overwrite files many times and have to click "yes" over and over. An option that says "Yes to All" or "No to All" would save considerable time and clicking.
You might also offer "Cancel Operation" from this dialog in case someone wanted to cancel out. I know there is a "Cancel" button on the main screen, but sometimes the pop-up modal dialogs come up so fast one after the other that you can't get to the cancel button on the main screen.
Thanks for considering this!

Thanks for the suggestions Rowland. I think these are good suggestions, ofcourse with the added bit of danger when clicking the wrong option. 😉 (@mabula-admin)
Just adding to this point. It's quite common that a "Yes to all" / "No to all" option exists for many computer operations, and the risk is on the user. Processing is basically a long batch process job, so there should be options applicable to such operations.
I've just walked away from a long multi-filter integration after making amendments, and came back to it only being 1/3rd complete because of a dialog box popping up.Â
Hi @rowland-f-archer-jr, @vincent-mod & @itarchitectkev,
I have added this to my TODO to make this better 😉
Thanks Rowland and Kev 😉

Ditto for this change. I made a change to the loaded files last night and reran calibration. I had to sit here for 40 minutes waiting for the overwrite messages to appear two at a time. With 5 sessions and 4 filters it took a long time.
