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.
Dear Mabula, all,
While trying to calibrate data, I ran into a critical warning during the process to generate a master flat image.
I think I found the source of the issue, but I cannot solve it. A few days ago I generated a BPM and master bias for my camera. I used data obtained from a Nikon D600 dSLR full frame camera, via an ASIAIR unit to do so.Â
Using the MB frame I want to calibrate some older flat frames I made in 2021 and generate a master flat. I know this is not ideal, but I could not find the MB I made back then, so I figured using the current MB is better than nothing.
Anyway, there is some issue in combining these old flat frames and the newer MB frame. It states that it cannot properly perform the flat field calibration properly and that the flat frames require a MB with the same ISO/gain as the flat frames. But this IS the case, since my MB frame and the flat frames are both shot with the same camera and at ISO400.
The only difference is that the MB is generated with Nikon D600 data obtained using an ASIAIR. The flat frames are obtained from my Nikon D600 camera directly. I see in the dimensions header that there is some difference between the MB frame and the flat frames. Next to the flat frames it gives a range of resolutions... But when I look at the resolution from the flat frames in windows explorer, it exactly matches the MB frame (6034 x 4028).

Am I doing something wrong, or is this possibly a bug in APP?
I am using the most recent version, 2.0.0-beta29.
Best regards,
Rob
Any help would be appreciated. Thanks.
