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.
Hello all. This is my first post and I'm on the trial version of the app. So far it's great and i'm loving it. I have used APP successfully on my MS Surface Pro laptop. It's great and works everytime.
The issue i have run into is on my 3 year old desktop. I thought it would be faster with a dedicated GPU with a nice i9 processor.
When I run it, I very often get a EXCEPTION_ACCESS_VIOLATION according to the logs. This usually happens in the middle of the analyzing stars step. It will get about half way through and then the app just disappears. No error pops up or anything. I had to go to the directory to find the error log. I have once been able to get through and successfully integrate, but every other time it fails. I tried this on both Astro Pixel Processor 1.083.4 Windows 64bit and 2.0.0 beta4. Sometimes it seems to crash may computer, sometimes not. But always the same error in the logs. I thought perhaps it could be a heat problem (my liquid cooling system hasn't been clean in a while 😐 ) but nothing else is experiencing this. I am running Windows 11 on both laptop and desktop.
Does anyone have any thoughts or suggestions? I can provide any additional info you need.
@clucernoni Hi Christopher,
Sorry for the trouble that you're experiencing. Could you please post the full crash report here? That should give us the info we need to help you solve this.

APP doesn't support processing on GPUs and I think there are plans to implement that in a future (but not the next) version.
Thanks, Wouter
@clucernoni Thanks for providing the logs. I have asked Mabula to have a look at them. He is currently traveling so please allow for a few days for him to respond.
Hi Christopher @clucernoni,
Thank you very much for sharing the crash reports. I have had a good look at them. They both originate from 1.083 I see and the crash occurs in different parts of the program. This indicates a RAM issue with a high certainty. The fact that you get the error at different stages and sometimes not is also very indicative of a RAM/memory issue.
Now... an Exception Access Violation is in fact a RAM issue. If you google for it, you will quickly find this.
APP should run without issues on a normal windows installation. Could it be that you have special security settings configured in the windows desktop computer? Have you run RAM diagnostics? To be clear, this error can be thrown due to a corrupt RAM module. If RAM was tested succesfully, perhaps a solution can be found here: https://thegeekpage.com/exception-access-violation/
