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.
Typically while I process in APP, the main screen shows a scrolling display of what the program is doing.
Well, this time, after a previous freeze up, I reloaded all my data and calibrated the frames. Then I pushed the "analyze stars" tab. Nothing happened. Haven't seen that occur previously. So after some seconds, I went ahead and pushed "integrate" knowing that it would put in previous tab tasks. Nothing happened again, blank screen. Then I looked in the tool bar and saw that the "other" screen, that is not typically displayed, was showing stuff happening, like "fixing file arrays". That screen is scrolling its data.
So, why am I seeing nothing on the main screen? I have not seen this happen previously.
"Error in module integrator". Well, I don't know how to fix that.
Guess I will close program, restart my computer, and load again from scratch. Â
Oeh, I've never seen that before. Sounds to me like something critical broke in the installation. Given your other issue with the crashing of the saved image, I'd advice to check your system for any hardware issues as well (scanning the harddrive and memory for instance).
