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.
Hello....I must be doing something wrong, I have tried several different pathways to try and have the panels register, but at no stage can I get past the Registration step. I have changed the settings in analyze stars several different ways with no success in passing the registration step.Â
Since this was a test just to make sure my framing was accurate i had limited subs, so I attempted to just load all of the lights and calibration frames, however when it gets to 80% in the registration step its stays there for hours on end.Â
I hope someone can assist me in getting past this step.
How does a frame look like, could you post a screenshot of that?
@japel Adding to what Vincent wrote: how does the frame, for which the registration fails, compare to a frame, for which the registration succeeds? Just open one first and take a screenshot, then open the other and take another screenshot. It helps if you make sure that the histogram also is in the screenshot.
Hi both, thank you for your replies. It looks like this is a me problem and not an APP problem.Â
It appears my mosaic frames do not overlap, and when I reshot with the express goal of creating this overlap the frames registered together.Â
@japel Glad that you found out what the problem was and that you were able to fix it. Yes, an overlap of 5% or preferably 10% is required for APP to create the mosaic.
