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.
To borrow from Maxwell Smart, I got THAT close! Just 10% more to finish integration of my 406 frames. I did get masters for the individual sessions. I had allocated APP 32 gigs, but not quite enough. I upped it to 48 gigs but had to shut down to access it and restart but all the in-memory stuff appears to be gone. What do I have to do to resume?
You mean you got masters for the calibration frames? Well that's a start. Are you using virtual memory? It probably should work, but I'm not very confident on that, how's APP handling that @mabula-admin ?
I have 64 GB actual memory. I reserved 32GB for APP, and I didn't notice it was approaching that until too late. I'd like a way to recover more gracefully. 🙂Â
I had it set up to integrate by filter and total. I got the by filter masters, it crashed when integrating all 406 subs. Kinda crazy to do that, but just wanted to see what happened. I'm thinking of reducing the Lights to be Integrated to 80%, believing it will then not use the lower 20% quality?
I like crazy processing to be honest, it is something APP should handle gracefully of course, so if it doesn't that might need a bit of attention.
Yes, I actually always do that, when collecting data I already tell SGP to dismiss any frame with a certain guiding error and then integrate like 80-90% (based on the total amount), resulting in the best frames to integrate. No need to go through them by eye then really. Do select to integrate based on quality.
