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, trying to process CR2 mono frames from a debayered Canon 40D.
The problem was solved last year in the " no interpolation in raw tab ". However this tab seems to have disappeared.
Is there another solution for processing mono frames.
Regards
Dave
Mmm, will have to get back on this, not entirely sure. What happens now, it's recognized as regular RGB and doesn't give you a mono picture?
Hello Vincent, yes that's what's happening. I used the trial about a year ago to process the mono frames from my debayered Canon 40D and there was a tab when loading for "no interpolation of raw files".
It seems that this is now done automatically depending on what is seen in the meta data of the frame. Of coarse APP can't know that the camera has been debayered, and sees in the metadata that it is RGB!
Hope I've explaind it correctly,
Regards
Dave
Hello again Vincent, just to follow up on my last post, I found my post from a year ago and the answer from Mabula so it seems that the possibility for overruling interpolation has been discontinued!
Regards Dave

Hi Dave, ( @davm)
Yes, indeed, that's the solution if the bayer filters have been removed 
APP will automatically follow the metadata, that will still APP that it's Bayer CFA data. So you need to overrule by disabling the interpolation, which shows you the raw data that you want.
Are the results after integration as expected?
Mabula
Hi,Â
Just idly browsing this thread and recall that on the Algorithm drop-down list on the Raw/FITs tab there is a No Interpolation option (first on the list). Could this be what you're looking for?
Mike
Owwww, how about that. I did look there but totally missed it. Nice find. 🙂
Ouch, I should have scrolled to the top of the algorithm list, great, problem solved! Many thanks Mike and Vincent
Regards Dave
