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 Mabula,
This is actually a solution, not a problem  🙂Â
For a long while APP ran very stable on my PC ( 4.2 Ghz 8 core with 16 gig ram. ) 4 days ago , in the middle of processing registration, the system crashed and rebooted. This happened with increasing frequency until I couldn't even complete registration. Â No problems with any other programs including PS, Star Tools, Registax and Astroart.Â
Interestingly, a process test of the CPU showed that all 7 cores run at over 95% during calculations. I found a program that stress tests CPUs. Â http://www.7byte.com/ Â - Hot CPU Tester 4.4 Â About two hours in, it found the problem...........Error in Fast Fourier Transform in Core 3.
I disabled that core in task manager. Straight run with 4 stacks no problems since.
I offer this as a possible path for anyone else encountering similar crashes - it seems APP is a bit rough on CPUs.
FYI, two PC tech companies told me you can't disable a specific core. Easy enough it turns out. Go into Task Manager while APP is running and uncheck the problem core in Affinity tab.

Hi Gary,

Excellent, always welcome 😉
I know about stress testing a PC, if a PC fails with a blue screen it means some hardware part is most likely unstable. So it also means that the problem is in the hardware or the bios settings for the hardware. Theoretically, you need to have settings that can run a stresstest for 24hours without crashing if you want to have a 100% stable system.
I have done some overclocking with my PCs in the past few years and from experience I know that if your PC can't handle a stress test with bios default settings, probably a hardware part is up for replacement ;-( I used to have my my icore i7 930 cpu overclocked for about 25%Â (2,8Ghz on 4 cores/8threads to 3,5GHz) and I never exeperienced crashes while APP was working for hours with high CPU usage, until one day I got a blue screen. I then ran a stresstest and after 6 hours I got a blue screen as well. I relaxed the overclock settings 6 months ago to only 12,5 %, ran a stresstest for 12 hours without problems. And in the past 6 months, I didn't get any blue screen on my pc using whatever software.
So yes, if users experience a blue screen while APP is working hard, they should look for the problem in their hardware/bios setttings, because it most likely means that some part of the system becomes unstable.
Kind regards,
Mabula
P.s. i have made this a sticky..
Thanks for this, I've been having similar issues on integration. The workaround I found was to dial down the threads to 1, causes it to run silly slowly but it gets there.
I'll give that CPU stress tester a go and see if it finds a similar issue.
Hello everyone, I got the last version at the weekend, but I got a bluescreen right away when opening app! Nothing has been changed on the hardware or something! I'm currently again with version 18 and it runs without problems!
CPU: AMD Ryzen 5 3600 6-Core Processor
RAM: 64GB

Right when starting up, that is also very strange and not something we've seen before. Blue screens can be a number of things, like hardware failures as stated above, but also driver issues. Can you verify if this happens with an other Java program or perform a stress test with another program?
There is very little changed between beta18 and beta19 so normally I would expect your Blue Screen crash to be caused by a hardware problem somehow. Can you confirm that beta19 does start if you try again? Or is beta19 always crashing? and beta18 never?

With version 18 I tried it again and was able to stack a picture. I closed APP and right after that re opened APP again and I had a BlueScreen again. I have taken some Stresstests with Cinebench and 3D Mark and no BlueScreens...
Very strange, we've not had reports of this being such an issue, so I still thing it must be a system issue. Can you perform integrity tests on memory and the disk APP is installed on?
