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 all,
I'm an absolut beginner with APP and have a question how to find the correct and best working settings for the Omegon veTEC 16000 C cam.
The cam uses a CMOS Chip (Panasonic MN34230). Are there other user around using this cam or a cam with the same CMOS Chip?
Thank you very much for your support.
Regards
Zav
In principle there shouldn't be special settings, unless APP is not able to see the mosaic pattern itself (in that case you need to manually force it to do that). Make sure to use darkflats for flats with exposure times of around 1-2 seconds, bias also with exposure times of about 0.5 seconds.
@vincent-mod
Thank you. I thought I have to use flats with exposure time exactly as the exposure time of the light frames?
Hi, sorry for the delay. No, flats simply need to have a proper exposure, not clipping the histogram on the left or right. You do need dark-flats (it's like a bias, but with exposure set to that of the flats).
