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've been coming up against a problem frequently, but not consistently. With some integrations, APP will get 'stuck' on analyzing one frame for LNC, for no apparent reason. It's only using 7% CPU, so it doesn't really seem to be DOING anything at all. I have an M3Max with 128GB of ram, plenty of HDD space.
This is actually most common on smaller integrations, in this case 3 frames of a mosaic panel. I use the same settings every time (unless actually integrating all the mosaic panels), so I can't really figure out what is causing this. Cancelling and re-starting results in the same hang at the same point.
I always let it go for 40-60min before cancelling, which is many, many times longer than it takes to completely process a much larger stack.
Â
Does anyone have any ideas what might cause this? Or what best practices are to fix problems like this?
Update: I let it go for 2hrs, and it never made any progress. I'm going to start from scratch again and hope for the best. They're all just RAW files, and they work fine in other software, so it's not a corruption issue...Â
Update 2: There appears to be no way for APP to continue to work. It will not complete processing of any image set I feed it, including ones I've already successfully processed.Â
I tried stepping back to the previous build, but that then throws a new error (repeatedly - you have to click okay ~20 times).
Â
Is there another place I should go for support? This is still happening on certain data sets, and the software is just... really buggy.
I know I'm doing things right, because about 2/3 of the time, it works flawlessly!
I took a risk and paid the subscription fee in hopes that I'll get some support to get this working, but I don't see any contact info other than this forum, which has no replies.Â
Josh,
There does not seem to be any support at present. Vincent is away dealing with a serious medical issue (see thread here: https://www.astropixelprocessor.com/community/main-forum/concerns-about-the-future-of-app/#post-31083 ) and Mabula seems to have vanished - which is very odd, unless something has happened to him too. No one knows what is going on I'm afraid.
Jon
That's certainly frustrating, but understandable on Vincent's end, of course.Â
Hopefully all is well with Mabula, and things can get back to normal soon...
Thanks for chiming in with that info Jon.
When doing a mosaic I normally will do the LNC on each set that I am going to toss into the mosaic, then stack the master lights and if it sticks on LNC I will stop it and then stack the masters again with LNC turned off. Just make sure to have advanced set on the normilization tab. Also, I have noticed if I have integration set to per session and all that can do the same thing so only allow it to do LNC per session.

It looks like Mabula is on a vacation. This is from his Facebook page. Lets hope he will be back soon.
