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 thinking of getting one of the new full frame CMOS cameras - some like the ASI2600mm have around 60mp.
Just wondered whether anyone is using APP to process the data from one of these cameras and what sort of spec machine is required to handle the huge amount of data involved?
I just began using QHY367c 36 megapixels, no problem with OSC but processing time much longer.
Soo any suggestion to speed up the processing flow?

I'm not an expert and ideally you need to trace the where the bottleneck is in your system, you will probably fix one bottleneck and that will allow you to see the next - its that sort of process.
I would look at RAM first - if you can add more memory, the faster the better subject to what your motherboard will take, that usually helps.
If you are using an HDD consider replacing it with an SSD which is usually easy to do and fairly cheap these days - but make sure you have lots of backups! Depending on your motherboard you may be able to go to M2/NVMe which may be faster than an SSD.
Faster processor - again depending on motherboard you may be able to put a faster processor in.
I'm not sure how much APP uses the graphics card but potentially there is something there that could help.Â
Solid advice! SSD for sure indeed, loads of ram and a gfx card is a good investment, but more for a future version of APP which is going to use it via Vulkan.
