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.
I posted this issue a couple weeks ago and have just returned to it. Initially, I thought it might be an exposure issue (overexposure reducing the visibility of stars in the image). I recently added a light pollution filter to my imaging train and it vastly improved the visibility of stars in the exposure, however I still received failed analyses. I also thought maybe my computer was running out of resources; my image files are around 95MB, so there's a lot of data to crunch. Then I remembered: support for Canon EOS R5 CR3 Raw files is still pending. I'm shooting with an EOS R5. The jpg versions process fine (I had two JPGs at the start of my lights, for some reason), but the CR3 raw files fail, even though I don't receive an error message regarding the inability of APP to process those files. At least that's what I think the issue is. I can either convert files to TIFF or wait for CR3 EOS R5 support. If I'm wrong, please let me know.Â
I am using v. 1.082. I've attached the analyze stars log.

APP should have support for the CR3 format, would you mind downloading 1.083 beta1 to try again? If that doesn't work I'd like to ask you to upload some of the data for us to check out. 1.083 can be found here: https://www.astropixelprocessor.com/community/appreleases/downloads/
Thanks, Vincent. I'll download the beta and check it out. In the meantime I'll upload some data for you to work with.Â
Dropbox File (Private or Invalid)Ahh, sorry I see now. I think APP does have CR3 support, but not yet for your particular camera. I think Mabula has data for it already, but to be sure I'll give him a sub of the data you send, thank you.
