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.
Hello,
Here I go again, trying to do a mosaic of 3.5 gb data, 10 frames. APP suggests to downsize as seen here, using 31 gb RAM.
How can I realize that APP works with more data, as other programs do like (very old versions of) PTGUI?

I’ve asked Mabula to respond as he know the specific reasons for this.

Hello Vincent,
that would be nice. Maybe he can have a look at this old issue from last year (...) as well:
remember? These are lightpollution and starcolor calibrated single panels (stacks) which end up with a strange color gradient which APP causes (Nikon dslr), doing mosaics. I have not found a way to influence the outcome when it appears.
Also I have encountered this:
where APP cannot register correctly two panels within a mosaic (only), as seen. This is also from a milkyway mosaic similar to the above. On serveral occasions this appears with different data. I have tried a lot to get rid of this but failed always. Maybe this has sth to do that I did a workaround saved the stacks as 16bit integer fit-files so that APP can work without this error from my first post here...
