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.
Check this video 😉

Why isn't there a method to download updates from within the program?
Probably because it's not implemented, if the program structure allows for that to be reliably integrated it might be something for the future, but in the way it's now it is less prone to bugs for instance.

Hi @brokeastronomer @vincent-mod,
I am planning to make this possible as well, including APP warning you that there is an update available 😉
Cheers,
Mabula
Cool, so... the program structure allows for it. 🙂
@vincent-mod), well it is more an implementation of making our server capable of communicating with APP about a possible update, and then uploading the new or updated files 😉 for the different platforms.
The structure as it is now, should not be a problem I think.

Update from the file menu would be great! also just a notification that there is and update would also do.
I have just downloaded version 1.083. Can I uninstall version 1.082? I am running MacOS Sierra 10.12.6

You can yes, or just drag it over it (which seems to work fine on MacOS). Mabula does advice to uninstall it first.
On macOS I never uninstall an old version first. When dragging the APP icon to the Applications icon, macOS asks if I want to keep both versions or replace the current one with the new one. I always choose replace and it has been working fine so far.
@wvreeven Thank You, Wouter and Vincent. I missed the "keep both versions or replace" option (I think I saw it when I switched from the trial to the paid version last year.) So I now have versions 1.082 and 1.083 in my applications folder. Is it too late to uninstall 1.082? Should I just leave it alone?
As you can see, I have little practical knowledge of what is going on under the hood. The program installed so quickly, I thought it was acting as an update rather than a new program.
Thanks again for your patience...
@maddenkeving APP is fully contained inside its app directory. You can simply remove the app directory for 1.082 from /Applications and it will leave 1.083 unharmed. You may want to rename the 1.083 app directory if it is not called AstroPixelProcessor.app but that's for you to decide. It will not matter if you don't though if you install APP in the future then you may not get the prompt to keep both or replace.
