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.
If I start an integration from scratch, it will begin calibration. If I click the Cancel button, APP will just hang there and do nothing. The only way to clear this is to exit and restart the application.
As it happens I did this as well last night and APP actually stopped calibration but continued with the next step (star analysis? I'm writing this off the top of my head). Canceling again made APP stop. It did not hang. This was on the latest version of Intel macOS.
@wvreeven In my case the app wasn't hung at the OS application layer, but none of the buttons in APP were available to press, except for cancel after clicking it. In the Load tab for example none of the buttons were pressable but APP was still active and responsive.
The same happened to me. I run the latest beta (29) on Windows 11. I canceled almost immediately after starting a multisession process. The program doesn't use resources and seems not to be doing anything but all the buttons are grayed out except the cancel button (and the license and cfg buttons). So I have to close the window and start from scratch. If there was an option to save setup it could have saved me about 15 minutes of my time.
