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.
Today it happened to me again: while I was integrating 2000 lights, the computer suddenly crashed, and I had to close the app. The problem does not rely solely on the crash, but there is no option to save the scheme of lights, darks, and bias... then everything is lost. You should have the option to save the entire integration skeleton of the different sessions so that even if the APP is closed, only one can reopen it and everything is ready to reintegrate. I hope this option is taken into account.
Another example of the use of this request. Let's say that I'm working on a project that requires multiple nights of capture, but I want to see how it's progressing when I finish every night... if this option exists, I just charge it and add the new fits files without having to redo the entire skeleton again... I think it would be very useful
Hi @hcdv Hector,
Thank you very much for your thoughts on this. Yes, this is being worked on, it is the feature to save/load a whole project. So yes, in the future, once APP is closed, a next start of APP should actually continue where you stopped the previous APP session, so it should keep all the analytical results and processing results that you had.
