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.
Mabula I have been processing like mad the last 45 minutes and not even a hiccup. Thank you for being so kind in helping me with this issue. It is seldom found where a company or product cares about an individual customer. I was a big fan of APP but am even more so now.Â
Thank you Mabula very much for your time and knowledge to resolve MY (NOT an APP) issue.Â

Superb to hear that Ray, thanks very much.
@vincent-mod
And thank you too Vincent for watching over this post and getting me to the right person for help.  😀Â
Mabula and Vincent
Guys after a week of processing and creating masters I am sad to report that the glitch does still occur. It only has been happening about every 5th use but always at the file load (Tab 1) and I have noticed that it does not seem to happen if I don't move my mouse fast or try to rush to add files where I may hover over a stray button. That may not be anything but I believe I read that when a user hit the details button and it caused the error to occur. Well being nosy I had to try that and behold instant crash. Now I have the glitch back with a vengence. Wish I had not tried that detail button trick. Â I did some searching and found that others had this same issue under the tread "Very Basic problem with interface-AMD Ryzen incompatability?". I read in that thread that there was a workaround that @Bcolyn had posted. He added -Dsun.java2d.d3d=false to the program somewhere and if that works it may be a perfect workaround for me. Is there anyway you can tell me where to put that command? I am not a programer but can go where I need to if I am grabbed by the nose and led there. Here is a screenshot of his post in the other thread.
 Any help would be much appreciated. Zoom call or taking over my laptop with teamviewer is fine as well.

@rayschilkecomcast-net the file is called AstroPixelProcessor.cfg and can be found in the "app" subdirectory of wherever you installed APP.Â
Close APP.
Start notepad (you may need to start it as admin depending on where and how you installed APP), open the file and look for the line that says:
-Dfile.encoding=UTF-8
-Dsun.java2d.d3d=false
Save and then start APP again.

directly below that line you add the line:
-Dsun.java2d.d3d=falseÂ
Save and then start APP again.
Thank you very much I will see if I can find that location and enter the command. Is your program still running well?
Thanks for getting with me on this.Â

my windows machine hasn't got any intel drivers or intel anything bar the nic so this problem on my machine wouldn't be that. It's all Nvidia

Well That was the answer. Seems to be running perfect. Thank you very much for your help and time. I can shoot tonight with my good laptop. For other readers I have an Alienware laptop with Intel processor and the Geforce RTX 2060.  😀 😀 😀Â
Thank you VERY VERY MUCH!!!!!
Best regards and clear skies,

Does your APP crash instantly when you hit the view change buttons when adding files? That triggered my crash instantly. I that line that Bcolyn had added to the config file was the answer. Might be worth a try. I saved the config file to a folder in case there was any issues so I could restore it. The speed of the application seems to be the same with no ill effects.Â
Attached a pic of the trigger buttons that were setting mine offÂ

@rayschilkecomcast-net. Mate, I am asking for another 30 day trial so I can check. It's been some months since coming back to this problem, life, bad weather so I haven't been astro-ing. I will see if I can get a trial again and check if recent nvidia updates over the last few months may have stopped it.Â
@bluknght You can ask for an extension to the trial you have, just mail Mabula at support@astropixelprocessor.com with the request and reason why.
thanks Vincent, yep I did message him on here this afternoon my time.
I just emailed himÂ
still happening now
Â
And did you check if you have maybe 2 gfx drivers active (Intel and NVidia for example) and things like that like is mentioned in this thread?
@13thmonkey Take a look at a different thread on here. I had issues that caused screens to start multiplying and the other thread had the answer that fixed it. Look in this thread for this shown in the picture. Worked instantly and never glitched again.  https://www.astropixelprocessor.com/community/postid/13637/
