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.
That's looking great! My advice would be to load the data of both in 2 sessions, each having their own calibration data. Then you can integrate like normal and have a combined integration of both scopes. If you assign the data to the proper filters, you should get integrated H-alpha etc results, which can be combined in the RGBCombine tool.
Thanks Vincent for your guide line
I have some data of M27, let's try to do the job, I keep you informed about the final result or, in a help if something goes wrong

was at module 6, 78% processing and this error come out, now it seems stopped, is there anything I can do?

I think you're running into a memory limit we still have, this will be addressed in a future version. I would suggest to make integrations of the Ha, OIII and luminance separately first, then load these integrations back in as lights (and setting the filters correctly) and then go to tab 5 (normalize) and press the "save normalized frames". These integrated results will then be registered and normalized and can be loaded into the RGBCombine tool.
Ok Vincent, for now I do as you suggested
