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.
Long story short, I lost my computer to a thief while passing through Oakland, CA on a family holiday. It was a Macbook with my recent version of APP which I routinely use.Â
I now have a Macbook M1, have downloaded APP again and need a user code to activate. How do I get this? Below is a screenshot of my prompt.Â
Thanks all

@kanadalainen Hi Ian,
Sorry to hear that your laptop has been stolen!
When you registered for APP (when you still had your previous laptop) you should have received an email containing your user code. Please look that up. If you cannot find the email anymore then please contact support@astropixelprocessor.com so we can send you the email again.
HTH, Wouter
@wvreeven Hi Wouter,
Â
Thanks again for your help. I did find the correct email, after some extra searching. 😀  All is well and I have successfully activated APP in my new laptop.
Now I need to figure out how to get back 2 years of light subs (my terabyte drive with organized data was also in the computer bag). 😉 😪Â I will look through the iCloud functions.Â
Anyway, I VERY much appreciate your help. APP with new star reduction is super nice, use it a lot.
Ian
@kanadalainen Hi Ian,
I am glad that you managed to sort it all out. Good luck retrieving your data. My image drive broke down once and I haven't been able to retrieve my data. I hope you'll fare better than me!
