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.
This was an absolute pain to put together. I had a total of 12 sessions in APP due to different cameras, optics, exposure length, orientation, etc. I mixed some stuff from Telescope Live in with a ton of my own data from both here at home and from trips to Marfa TX. All of this integration was taken with the Telescope Live AUS-2, CHI-5, CHI-6, Pentax K5 with Samyang 135 f/2, Pentax K5 with Borg 55FL f/3.6, Pentax K5 with WO Redcat 51, Pentax K3 with WO Redcat 51, and Pentax K3 with Borg 55FL f/3.6.Â
It's an absolutely amazing result. So many sources, each with it's own distortion and coverage. Beautiful image.
It honestly shows how powerful APP is when it comes to this stuff. This one even won the AAPOD for December 22, 2022. All 5 of the AAPOD I have gotten were processed in part at least with APP.
