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 Folks
So, I'm sure it must be something I'm doing (or not doing!) I'm trying to follow Mabula's video to create a multi channel mosaic - and it's gone well right up to the point where I try to normalise the panels. The RGB was shot just as such, with an OSC camera, the Ha panels were obtained with the 'extract Ha' algorithm after using a quadband filter. If I try advanced normalisation I get this message on screen:
It looks like it may be generating two of the same kind of message possibly? If I then try regular normalisation it generates this message instead:
I'm tearing my hair out here - I'd really like to use the Ha panels to see how it comes out in combine RGB, but I don't know what's going wrong. Help!
Thanks in advance

I believe this is the solution to the problem.
@minusman thank you, strangely enough I was just thinking about splitting the rgb channels and trying it that way - I shall do that now and see what comes out the other end!
Fixed! Thank you so much @minusman for pointing me at that post.
As per the comments within the aforementioned other post, I was trying to combine OSC RGB data with (albeit channel extracted) monochrome, which is outside of the remit of APP at this moment in time. SO, I split the RGB channels after stacking each individual pane, then proceeded to register/normalise/integrate from there - and I have a mosaic 🙂Â
It's only the basic stacks combined in the combine rgb tool using the HaRGB1 setting at the moment, but I'm very happy to have got this far and looking forward to finishing the image. Thanks Mabula, I love working with this program (well, when I get it right anyway 🤣 )
Glad to hear it worked out now. The mosaic looks pretty good already. Maybe with the extended normalization, try it when you create the mosaic. And play with the settings of MBB and LNC, maybe the stripe in the middle of the mosaic will disappear.
With best regards
