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.
When loading lights from last nights session I was treated to a new and unpleasant application behavior this morning. A "Gathering Frame Details" window pops up - and stays up, frozen at 3% progress. I may have seen this window before, but it appears and disappears so fast it is virtually subliminal.
The console shows the app running at 13%. The Lights do not load. I am unable to load my flats (or anything else).
In this state I can switch to other tabs and activate various pop-up menus. But all of the buttons to execute a tab (Create Masters, Analyze Stars, etc.) are not active or selectable. (Which makes sense since no flats, darks, or anything else is loaded.)
I am using version 1.083.2 on a 24" M1 iMac, OS Monterey 12.2.1.
I think the answer just popped up on the screen:
Â
And to complete the story - excluding that file, the other 24 lights loaded successfully and things are running normally.
Great, how long did it take for that warning to pop up?
@vincent-modÂ
I did not put a watch to it. Long enough for me to click around to the other tabs, do a screen shot, then write that first short post.
Five to eight minutes?

No problem, that I think is too long for a check like that, I'll inform Mabula. Thanks for sharing!
Would you mind uploading the corrupt file to us? Curious to see if it happens here as well or if it may be an issue on your system.
I would if I still had it. I reformatted my acquisition thumb drive for the next nights imaging and emptied the trash on my computer. Given the amount of writing I am doing, not sure it could be recovered.
Since I started imaging last August, this is the first time I have seen this.
Ah well, no problem. 🙂 If you ever get it again, we'd love to have it, just to see if APP is choking on something there.
