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 am doing a mosaic and noticed that while APP sees all of the installed ram, but it doesn't seem to see both CPUs and is only using one of them, which is confirmed by task manager. Is there any way to fix this?
@imnewhere Hi, this seems to be related to hyperthreading (or a similar technology). And it looks like you are using APP 1.083-4. Is that correct?

I am using 2.0.0 - beta 4 on this one. As far as hyperthreading goes if I use it on my main desktop it sees all of the threads too. On the main desktop I run a xeon e5-2699v3 and on the other computer I run dual xeon e5-2696v4 processors. I have attached one from the main desktop where it shows that, and you can see on both they refer to threads rather than cores. I have attached screenshots from the relevant part of the screen from both computers since I run the other one as a remote desktop.

Hi @imnewhere,
Thank you very much for reporting this.
I have added this to our ToDo list to investigate if it is possible to have APP use all avaliable CPUs and thus all available threads.
I know that I investigated this a couple of years ago and back then it was possible but only with commercial Oracle license meaning that an APP version having that capability would be more expensive for sure. Maybe things have changed though so I will make sure to check this soon and will update you on my findings.

Thanks! If you need me to test anything let me know. I built this machine specifically for processing.
