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 have a 1-terabyte drive I store my imaging data and another similar drive with just the programs. I am running into problems with APP not having enough working space on the first drive for large integrations, even with 159gb available. Can I set the other drive, which has 750 gab available as the working drive? If so how?

@whixson Wayne, when you choose a working directory when APP is started, you can choose the external disk and APP will then use that for all temporary data. Keep in mind that this only works well with SDD’s. There is a huge amount of data involved with processing in APP and non-SDD’s are not fast enough to keep up with the I/O generated by APP.
How big is the data set that you are processing? If 159 Gb disk space is not enough then that suggests that you are processing quite a lot of data. Can you split it into multiple parts and then combine the results of that into one, final, result?
thanks! Yes, I forgot to mention they are high speed SSDs.
That’s what I’d hoped. I have a QHY268C camera with 26MB files, and when I take several nights’ worth of 3-minute subs, it ends up taking lots of room. I could split up by night say to create masters for each night, but not sure if that’s as effective as multi-session processing all at once.
I also need to step up to something like a 16-core CPU and high power GPU and 128 GB storage!
thsnks, Wayne
