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 is probably easy, but I am working on some mosaic 2x2 and if I integrate say all my images one panel and a time into a master integration for panel 1, panel 2, panel 3, panel 4, then do it all as a mosaic it works out great. But I seem to have to do them independently and then remove that panel 1 set of lights, then add panel 2 and do it, then remove them and do panel 3.
Â
IF I add them all at once and tell it to kick out per session, it does them as a session individually, but with the entire black empty sections of panel 2, 3, 4? If that makes sense. It's not cropping it down to just session 1. So when I go to integrate those master lights as a 2x2 mosaic, it swirls it all to death.
Â
Is there a way to do panel 1, panel 2, panel 3, panel 4 all together BUT have it kick out each in it's own 'session' master AND have it cropped and registered to only that session as if they were done independently?
Â
hope that gibberish is making sense.
@jjones Hi Josh,
This is a very good question. To my best of knowledge this is not possible currently with APP. I have asked Mabula to confirm this.

Hi Josh @jjones,
"This is probably easy, but I am working on some mosaic 2x2 and if I integrate say all my images one panel and a time into a master integration for panel 1, panel 2, panel 3, panel 4, then do it all as a mosaic it works out great."
Yes, that is the recommended workflow for sure 😉 It is for sure the most robust and fastest way as well, especially for much larger mosaics.
"IF I add them all at once and tell it to kick out per session, it does them as a session individually, but with the entire black empty sections of panel 2, 3, 4? If that makes sense.

Indeed, this is not how you want to process it in the current APP versions. This has to do with mathematics and optical distortion correction in the way it is currently implemented in APP.
And to clarify, if you load all frames of all panels, the Field Of View of all the integrations of your panels will always be the mosaic Field Of View (FOV). I think that you are asking to have 4 different FOV's, 1 per session, right? I don't think that is something very usefull to implement, since the advised workflow already easily gives you that. It would only complicate the possible settings and integration options more I feel.
In the future, your request to load all frames at once and get a good mosaic will become possible, but only after a big update of the registration engine.

@mabula-admin ok, I just wanted to confirm I wasn't missing something.Â
Reason I ask is when setting up a lot of images, say from a RASA, it may run for a while, and in this workflow, I have to come back, remove panel 1 images or unmark, then just integrate the next set...
If it handled sessions independently, then I could leave it and have it do all 4 panels in a night, or 9 panels in a 3x3 and kick out nice individual panels.Â
Sort of how it does it by filter already in one full run but kicks out individual filter images cropped.
As it is, I have to go back and just set it to integrate that panel, then run it again, then again... if that makes sense. I'm super happy with results on it though.
Dear Josh @jjones,
Sure, yes, that is the advised workflow for APP at the moment for mosaic processing 😉
At some point this will be greatly improved with a new registration engine that will be able to manage your suggested workflow.
