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 đŸ™‚
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.
It would be nice to be able to stack all panels of a mosaic in one go, instead of processing all the panels one by one, especially on a slow remote connection ...Â
So load/que all the panels and let APP process them all, it would be a huge timesaver.
The end result would be that you have the individual panels ready for final mosaic integration ready to go. (Icing on the cake would be that you could even that happening automatically but that would require other settings so I do understand that this would be a huge undertaking)

This is already possible and usually the way to go. It is one of the key reasons to use APP. However, if you have a LOT of images per panel for the mosaic then the recommendation is to process them panel per paneland then create a mosaic out of them.

It's not possible, you confuse stacking all panels in one mosaic in one go ... it takes ages especially if you use LNC, so no it's NOT possible and it's a feature for people that do lots of mosaics. Stacking individual panels and then combining them to a mosaic is MUCH faster. I'm doing a small mosaic 2x2 with LNC 6 it 4th and it runs ages on my 120 subs ... not usable. Why do I do it this way, because I cannot stack the individual panels in one go and my setup is remote and I do not want to babysit ... I loose on average a day per dataset ....

Technically speaking I am right. It IS possible and I have done it before. Load all lights, flats, master dark, master darkflat, master bias, bad pixel map and out comes a mosaic. That’s what you are after, right?
And like I wrote, yes it can take a LONG time. I agree that optimising that process would be a huge benefit. So, practically speaking you are right.

I do it as well does it work, yes, but it is slooowwwww like a day or more, when I do it manually 2-4 hours, so I know what you mean, hey I was one of the first contributors of data so that Mabula could test mosaics.Â
So please stop, we real mosaic people, from getting a feature we want, I have fellow astro imagers at my remote site, he want's it too. If you only can gather data ones in a while it's no issue but with a remote where all needs to be processed remote with a slow line, where your teamviewer session is barely usable and you sometimes gather lots of data, well you want bulk stacking of panels, PERIOD!

And another thing, try to do this with a 60MP camera, do the calculation you will see it's impossible to do in one go.

So, I'm away for a bit and some posts almost explode. đŸ˜‰ Let's keep it a bit relaxed, the request is clear and would be interesting to see if Mabula can make something like that happen. Technically APP already makes a mosaic in 1 go, but indeed doesn't sub-stack panels before making the final mosaic. It might also not even be necessary when GPU acceleration is added, so that's for @mabula-admin to answer.
