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.
due to a computer crash (windows 11), I had to install APP new and I used the latest update. However, this was in my hands not functioning, with several windows mixing up etc.Therefore, I went back to the last stable 1.83 version. However, this changed the analytical graph completely and I see for me a disadvantage. I am very dissapointed that I cannot delete frames within this graph. Will you keep this garph in the future?

Hi Peter @peternb,
Thank you very much for posting your issue on our forum.
I think that the issue that you face is that both APP 1.083 and APP 2.0.0betaxx are installed at the same time on your computer. Are they?
We know that the windows registry creates very weird problems like this if you install both the old 1.083 version and one of the newer beta versions.
To solve this, you first need to uninstall all APP versions that are installed. So install APP using windows Remove programs/applications from the control panel. Then double check if another version is still installed, maybe you still see a reference to Astro Pixel Processor when you open the windows Start menu? That APP installation needs to be removed manually then.
After having cleaned the APP installations, you can safely install APP 2.0.0beta36 and this should work perfectly on Windows 11. 2.0.0-beta36 is much better and faster than 1.083 and soon we will stop support for that old version as well once APP 2.0 is officially released.
Of course, the graph will be kept and will be further improved going forward as well.
Please let me know if this solves your issue or if you need more assistance.

Hello Manula, thank you for your repons.Â
My windows 11 was installed some days ago and working fine with all my programms including Pixinsight. It is a not too old computer (AMD Ryzen 5 5600G with Radeon Graphics 3.90 GHz, 32 GB RAM). I just deleted the only installed APP version 1.083, as I mentioned, and downloaded now again the "latest release Windows 64bit version" as found on top of your download list.Â
So fine, so good. I just made a first test, loading up LRGB frames from M 13, which were stacked successfully yesterday with the 1.083 version. After entering all frames and Masterflats etc and klicking on "intergrade" the version crashed immediately without showing tje awaited input field for the file name for the stacks. As I now remember , that happend also the last time trying this version. Last time with this version, I reentered all files again and then it began running but the windows were mixed up.Â
My facit is that this version is not stable in my hands, whatsover.
I now loaded Version 2.00 beta9 (04.Jan 2023) and this stated, using the same files, correctly. I will see what comes out.

Hi Peter @peternb,
I am not sure what is happening on your computer but it does sound like a problem with different APP versions being installed at the same time somehow. If you remove APP from the computer, please double check the installation paths, maybe some version is still there although you think it is not.
Double check these paths please:
C:\Program Files\AstroPixelProcessor
and
C:\Users\[your windows username]\AppData\Local\astropixelprocessor
and
C:\Users\[your windows username]\AppData\Local\Programs\AstroPixelProcessor
Make sure that all locations are empty, if not, clean them manually. The AppData folder is a hidden folder, so you need have the windows explorer show hidden files, than you can see and enter these folders.
Also remove any reference in the start menu to Astro Pixel Processor and Aries Productions.
Once everything is clean, please try installing 2.0.0-beta36 again. When it is installed, please click on the LICENSE & SETTINGS button, and at the bottom, simply reset all settings and menus. Is everything working fine then?
On our test systems with windows 10 and 11, all is stable and better with beta36 compared to the older versions.
