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.
Hi guys...
I recently loaded 256 Lum frames of M31 (30 sec subs) into APP together with master dark, master flat, master bias and BMP. When star analyses was completed, the software stopps... not possible to continue. I tried to increase CPU to 12 and restarted the PC, but same result. Could it be the number of frames that is too high??

Not to be expected no, but it just stopped you say, it really didn't have any activity anymore that you could notice from the system? How much memory does your system have?
In the mean time you can always give it a go with just 50 frames of course.
Hi...
Many thanks for your suggestions. My system is 32Gb memory. I tried with 30 frames and that worked fine.... I guess this means that it is the system that limits the number of frames that can be processed in one batch. I shall have to split the bunch of frames in smaller batches containing ~50 frames or so...

Hi again...
Forgot to say that I was running ver 1.079, but have just upgraded to ver. 1.082Â and yes the program stopped completely and could not be accessed. I had to use Task manager to shut it down (although other programs ran normally)...
AJ
With 32GB that shouldn't be a problem though. I'm wondering if it indeed was stopped, maybe there was a dialog behind a window that required attention for instance? I would suggest to try again, and otherwise you can make integrations of 50-ish indeed (to get the data divided nicely) and load those results as lights again and integrate them.

Ok, well I would try it again then as that should work I think.
