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.
Hi, I am really happy there is finally support for the R6 cr3 files. THANKS!! I have made good MD and MB but something is messing up my MF. Can someone take a look at my files please and see whats going on? I'm getting a pure white image on my MF. The individual flat files look good tho. Using a high thread count white t-shirt over the camera lens, in a dark room using the display on my MacBook Pro as I have done successfully many times in the past with refractors and camera lenses.

What APP version are you using at the moment? We'll have a look as well, please allow for a day.
Latest version! Previous ones I could not use R6 raw files.

I requested access, but didn't get it yet I think..
@vincent-mod Hey should work now, here is the link https://drive.google.com/drive/folders/1OScZVCsV-7x1mH4ykh17DewoLYzwxXL-?usp=sharing

Thanks, downloading right now, please allow for up to a day of processing.
Ok, so for your flats you'd also need a bias or darkflat with the iso and exposure length (and same offsets etc) as the flats. The bias you have has a different iso, so that may already cause issues there.
Besides this, there's also something going on with the bias (and probably dark then as well). The mean values are very high on it, if you load in 1 masterbias APP will still use it and due to the high noise level, the flats are not calibrated properly. There are some weird normalization factors applied by APP to convert from 14-bit to 16-bit. Could you explain how exactly you made the darks and bias (what software etc.) and what steps you performed before the masters were made? Thanks!
