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 tested beta41 regarding the error in https://www.astropixelprocessor.com/community/main-forum/beta40-problem-error-warning-when-using-lnc/#post-34155.
The integration of the 460 lights was performed flawless with LNC 1st degree, 3 iterations and Bayer drizzle 1x, 0.85 droplet 🙂
BUT 🙁
Since in the 460 lights there are some lights that are not so good, I thoght it would be a good idea to integrate just 75%, which are 345 lights. So I dont restart the programm after finishing the 460 lights but set the slider "lights to stack" to 75% and startet integration. Integration started, and after about 3 lights a SUDDEN CRASH happens 🙁
Hi @juergenn,
That sounds like a very other type of crash, more like instability with hardware or even the software layer between the OS and our development platform. Maybe you can run in the following way to produce an error log that should help us:
Windows and MacOS:
or Linux:
Try to reproduce the error and send me that log file, hopefully I can pinpoint the cause of the crash then. If you can not reproduce the crash, or if it happens more randomly (not at the exact same moment in processing), it will be very likely instability on you system, in that cause you need to check the ram modules and possible overclock settings.
Let me know if this helps.

Hi Mabula,
I just restartet APP and set the 75% from the beginning. Now I'm at light 100 of 345 and it seem to work now. Since its still running I will tra again first 100% directly following 75% hoping the crash happens again. I will try to use your commands you mentioned above.
Hi,
I did the test and rerun APP, starting with 100% of the lights, then 75%. Now all went fine 🙂
What I'm wondering is that when closing APP the following message appears (but until closing APP all went ok):
#
# A fatal error has been detected by the Java Runtime Environment:

Thanks for fixing the beta40 issue so fast 🙂
P.S:: I'm running Opensuse 15.6.
I installed it via RPM
Okay thanks @juergenn,
Can you send me that /tmp/hs_err_pid3655.log file if you still have it, can you send it to support@astropixelprocessor.com ?
I will have a good look at it, it could be something related still to incompatibility with Linux Wayland or OpenSuse perhaps. Is your linux installation using Wayland?
Next release, we will again move to a newer platform, JDK26, it should again enhance performance and give better compatibility with the new Linux versions.
