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.
When running Register with Save Distortion Model it gives the error shown. Only the first time it is run, if I just run it again it saves the profile properly.

Hi Steven @mrrat,
Thank you very much for reporting this. Is this error repeatable? Does it happen every time that you try this? I will try to see if I can reproduce the error. Â At first look, it seems that registration the first try failed somehow and the 2nd try worked fine.

@mabula-admin yes, I repeated the process several times to capture the error details
Hi Steven @mrrat,
Okay, I have added it to our Issue list to solve this a.s.a.p.. If I need more info or your data to test this, I will let you know.

Hi Steven @mrrat,
I have found the bug and fixed it for the 2.0.0-beta38 release 😉 Thank you very much for reporting this.
- IMPROVED AND FIXED, 4) REGISTER, SAVE OPTICAL DISTORTION MODEL
As mentioned in this thread https://www.astropixelprocessor.com/community/main-forum/saving-camera-profile-solution-contains-uncountable-numbers/#post-32820 , there was a bug when you try to save an optical distortion model. We have fixed this bug. We have changed the names of the settings for the optical distortion model saving and have also improved the tooltips and the dialog that asks for your camera and optics names to be able to save the optical distortion model. The camera name and optics name for the model are also remembered per APP session, so you won't need to re-enter them if you make a newer model with the same setup.
