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 want to add data from a mono camera to data I already collected with a OSC. I extracted Ha and OIII from the color subs. Is it possible to combine the newly collected data?

Thanks
@tempusfugitxxii Yes this is perfectly well possible. First you should process the mono data as you normally would. When done you can load all mono and OSC integration results as lights (don't load calibration data), go to tab 5 and click the normalize button. APP will execute the intermediate steps automatically. When done, save the normalized files in tab 5. These will be registered and normalized with respect to each other. Then you can load then in the combine RGB tool and process them as you normally would.Â
Thank you for this but I don't see where the data for the same channel would be combined. Ha with Ha, OIII with OIII. Isn't the RGB combine meant for combining DIFFERENT channels into a color image?

Thanks
@tempusfugitxxii It wasn't clear to me that you want to combine Ha and OIII data from different cameras. You can load all Ha integrated results (without post processing them first) into an Ha channel in session 1 and all OIII into an OIII channel in session 1 (no calibration data), go to tab 6 and click the integrate button. You'll then get two integration results that you can process further.
@wvreeven I tried your suggested technique. APP does not register the 2 images correctly. Stars are offset in the combined image.
