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 need a little help figuring this out. I am shooting a 9 panel mosaic using Ha, Oiii and Sii. I am shooting about 10 frames for each of the filters, so 3 times 10=30 frames per panel so, I should have about 270 total frames to put together. This doesn't seem like a huge amount, but it is kicking my butt.
What I have done so far is process the frames for each filter per panel. For panel 1 I have a single processed Ha, a single processed Oiii, and a single processed Sii. I have these processed frames for each of the panel. Â
My laptop has 32gb of ram. I am shooting with an ASI 6200mm, so the file sizes are large. I have ran into troubles with everything from not enough disk space to needing more ram to process this. Whenever I have been able to get a processed mosaic, the backgrounds between the frames are very different and apparent. Â

Help! How do I process this and put it together with out buying a huge computer??

If the subs are really big, it may be that that will create a limit on resources, unfortunately not something that is easily fixed. Having a big internal SSD will help, otherwise you likely do need to downsize the mosaic (it usually asks that as well I believe, otherwise there is an option for that). Having the Ha, OIII and SII integrated is very good, I would then first create a panel from those together. Do you do that? Only when I have the final panels, I would then use those to create the mosaic and for that you need LNC and MBB as well.

Thank you so much for the assistance. I will try the downsizing to see if I can get it that way. I MAY need to buy a new computer. I really like the idea of building these mosaics and hate having to deal with issues.
