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 trying to register this error occurs about 57% of the way. Using a 612mm FL and 3.76 pixel size full frame ZWOASI6200. I've tried different settings to no avail. Using the calibrated projective. Star analyis is 5000. Any suggestions as to how to get these frames registered because that's as far as I can get (49 frames total LRGB). Thanks for any help in advance.

Hi Gerald @gmillerok1,
Thank you very much for sharing this issue.
I recognize the error, it means that APP has trouble with registering the full mosaic, Some frames are difficult in the APP version that you use. Which version are you using? I think it will older than 2.0.0-beta38? Did you try with 2.0.0-beta38?
For 2.0.0-beta39, which will be soon released, i have worked extensively on a new registration engine with new mosaic algorithms. Please check the release notes for this work in progress still: https://www.astropixelprocessor.com/community/release-information/astro-pixel-processor-2-0-0-beta39-release-notes-work-in-progress/#post-33139
I have solved many bugs and problems with mosaics in beta39 and it will be really helpful if you can upload your data here so I can test it and report back to you. If all works fine in beta39, I can provide you even with a beta39 test version so you can already process the data.

Please make a folder with your name and issue like: GeraldMiller-mosaic-issue
and upload you data there and let me know once done. I will test as soon as i can and will report back.
