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.
Hi guys, I just got Askar Color Magic C1 and C2 filters. I took one session with C1 and another session with C2. How should I stack them in APP before processing them in PI? I always use one filter session with my ASI533MC so I've never done this before.
Thanks!
Integrate C1 data with 0) algorithm
-- Ha-Oiii extract Ha
-- Ha-Oiii extract Oiii
--> this gives you Ha and Oiii
Integrate C2 data with 0) algorithm
-- Ha-Oiii extract Ha (this produces Sii)
-- Ha-Oiii extract Oiii
--> this gives you Sii and Oiii
Â
In PI combine the two Oiii.
Put together Sii, Ha and the combined Oiii = SHO.

Hope this helps,

Hi @astrotal & @maxthebuilder,
Or combine the Ha, SII, O3 directly with APP's RGB Combine tool ?
Mabula
This, of course, works too.

Instead of processing the C1 data to extract OIII and then the C2 data to get the OIII, could you process both C1 AND C2 data together to extract OIII?
@tstevens83 Â Since OIII only happen in G and B color, I think you can do this with Put all of them together and extra OIII and once.Â
But for Ha and SII you need to separate them twice.
