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.
For some reason APP has started asking me for the activation detail upon opening in Windows 11.
Obviously a glitch has occurred somewhere. I have tried a reinstall but it is still happening.
I would like some advice to correct this, please.

Dear Frank @thedwo,
Did this occur after updating to windows 11 or perhaps after a RAM upgrade?
In both cases, APP will think that you are running it on another computer and so you need to re-activate.
Another reason could be upgrading to 2.0.0-beta26, we fixed a license management bug in this version which can force a re-activation on some computers.
Simply use your license details to re-activate APP and all should be okay, did you try this?

I installed the latest beta26 several times, with the same happening. I then left it for couple of weeks as our weather has been dreadful (OK for fish and frogs) so had no data to process. Then yesterday I installed APP using a proprietary Uninstaller and then reinstalled beta26 and now it seems to be working OK.
Difficult to tell what the culprit was, but working OK now. Thanks for your help.
Frank
Hi Frank,
Okay, I am not sure what you exactly did to solve the issue? Can you share a bit more about that?
I am glad all is okay now on your system 😉

Hi Mabula
APP went through the asking for activation probably 6-8 times in all. After several tries, I then re-installed APP. With same result. I then left it for several weeks, as our weather was rubbish and did other stuff. Then when I got back to it, I used a proprietory uninstaller and removed APP. Restarted the PC and installed APP. It was then working OK.
The only thing I know happened during this episode was several updates to windows 11. My conclusion is that this wasn't really an APP problem direct but a conflict with an interim windows update on my PC.
All's well that ends well.
Thanks

Hi Frank @thedwo,
Okay, thanks for that info, yes, this is probably a windows registry or update issue somehow then...
