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 all,
Since I am using an old laptop with an NVIDIA GT520M graphics, it only
has 48 Cuda cores which is close to nothing in terms of nowadays graphic cards.
Once APP uses GPU processing, would I notice the effect of speed improvement
with this small amount of Cuda cores?
Just for interest!!
Thanks for any insight ( and hopefully some expected timeframe for the future
release with GPU processing implemented )
Stay well,
Mert
Well, I have no idea to be honest. 🙂 I'm not sure how much more efficient the GPU is to make up for the fact yours is a lot less powerful to more modern ones. That will be something to just test I think, I'm assuming you can then still select not to use a gpu whenever it's supported (I have no actual view on the feature path).
Thanks Vincent,
I know it is hard to foresee! Is there some timeframe for the release of APP
with GPU processing implemented?
Stay well,
Mert
I don't dare to give a date-range, might still be a year as it's a big operation but I really have no good idea. Sorry.
Ah that's a pitty, I'm busy configuring a new desktop workstation
with a lot of cores and cudas in order to get the most out of
APP and Pixinsight.
So very likely it might take some other year to get implemented?
Hope to see that version making processing much faster!
Stay well!
Mert

It might, but I really don't have a clue on this in particular. Sometimes Mabula is finished with a large development cycle and suddenly implements something I thought would take a while still. 🙂 But it doesn't hurt getting a good gfx card, we plan to support both NVidia and AMD.
