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 recently bought an owners licence and the program asks me to enter the details including the code almost every time I start the program. It also appears to think I am using multiple computers, however I have only installed and run it on one computer. My computer is running windows 11 but it seems to think I also have a windows 10 computer.
Interesting, never seen this before like this. I'll forward it to Mabula and thanks for reporting!

Hi @ronroper1601,
Windows 11 in fact was still reporting it was windows 10 earlier, maybe with an update of windows 11 it is now fixed. So this is due to windows 11 and not APP code.
With regard to having to re-activate your license, I can only assume that you are installing APP not correctly somehow. How do you install APP?
After installation, is there an APP license file in your Operating System user directory?

@ronroper1601 you should avoid to show your license codes to all people. someone could use it...
Hi @mabula-admin, thank you to you and others who replied to my question. I am not sure what happened during installation but I just did what I thought was a normal install. However I have now noticed a couple of odd things. There are 2 APP shortcuts on my desktop, each has a different starting location.
Shortcut 1: Target: C:\Users\ronro\AppData\Local\Programs\astropixelprocessor\astropixelprocessor.exe
Shortcut 1: Start in: C:\Users\ronro\AppData\Local\Programs\astropixelprocessor
Shortcut 2: Target: C:\Users\ronro\AppData\Local\AstroPixelProcessor\AstroPixelProcessor.exe
Shortcut 2: Start in: C:\Users\ronro\AppData\Local\AstroPixelProcessor
The shortcut 1 seems to operate correctly while shortcut 2 produces the licence issues described previously.
I think shortcut 2 may have been created in March 2022 when I tried APP as a trial version. I had forgotten that I had already installed it, so reinstalled recently when I purchased the licence.
I assume I could just delete Shortcut 2 and the associated files for that path. I checked in Settings/ installed apps and there is only one instance of APP showing and it is v2.0.0 beta 9 so I will not uninstall anything from there.
I do have a APP-License.lic file in my user directory dated 17/01/2023.
Many thanks
Ron
Hi Ron @ronroper1601,
Yes, the shortcut 1 is the APP 2.0.0 version, whereas the shortcut 2 is 1.083 probably which has a bug even with computer identification for license management, so that really explains it.
Indeed, simply remove shortcut 2 and the shortcut 2 target and all will be okay !
