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.
I'm running out of RAM when integrating large data sets. I have an F/2 imaging system so my exposures are short. I have 16GB of RAM but can't integrate more than 300 or so frames from my ASI183MM. I have several data sets with 600-1000 frames.
Is there anything I can do to integrate this data? Would I loose anything by doing 250 frames at a time and the integrating the resulting integrations based on exposure length?Â
Could APP warn me before I spend 3 hours integrating data just for it to die at the end? Could SWAP space be used on my SSD instead of just dying?

I had the same issue processing a large data set of 1000+ images. I have 32 GB RAM and had to max it in APP in order to get it to go through. But I actually made several attempts increasing it a few megs here and there, until I got tired of waiting 5 hours for it to process only to find out there was not enough RAM.
When integrating so many frames, it's better to divide the frames into sub stacks of say 200 and combine those later.
ps. Mabula is also aware of this issue, it seems to be a problem when using LNC. Did you have that on?
