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.
It appears if I don't delete the individual dark and bias frames APP will reprocess them even though there are masters loaded.
That shouldn't happen, are you sure it is doing that? Is the below option selected in the "Load" (1) tab?
Yes, that is checked but so is the "Create Master Bias and Dark" in the Calibrate module if that makes a difference.Â
That shouldn't make a difference. Very interesting, could you give more details about APP version, platform and what exactly you did to create the bias- and darkframes?
Sure. Pretty much loaded all the individual bias and flats into the loader and ran a series of lights through the integration process. This Created masters. I then cleaned out the lights and loaded more lights from the same camera that would use the same masters. Clicked integrate. It started by created new BPMs with the master darks already there but then went through the whole Calibration process recreating the masters. I'm on Windows 10 with APP version 1.068
Another problem. I started a Ha mosaic. I created 4 panels with APP through the integration process. When I cleaned out the lights and loaded the panels, APP did not recognize them as lights unless I disabled the Recognize Masters and Integrations checkbox
