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.
Version 2.0 Stalls when Processing One Shot Color Imagers on iTelescope.net
This is a reprint of a discord msg left on the iTelescope Discord Server to their staff. Â Hope this can be of help here.
"Thought this might be of interest. I have downloaded the new beta release of APP and have found that it stalls and or fails to process the Color images on T02, T68, (did not try T69). Starts slowing down early but stalls completely on integration. Admittedly I have a bare bones iMac (see attachment) was never able to multitask on 1.083.2 but it made it through. I have to reload 1.083.2 to process color images. Hope this helps, don't have a contact email for Mabula so maybe you can pass this on. Hope this Helps"

Thx for the quick response, by mutlitasking I mean I need to quit all other tasks Safari, Pages, etc to stop APP from slowing down or stopping with some images when using 1.083.2 or previous versions, even that does not help with 2.0. Â At this time I am having the issue with just the color camera images as I said, haven't done much else in LRGB or SHO yet.Â
These are standard iTelescope calibrated image files for T02 and T68, i.e.
