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 đŸ™‚
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,
For some time now, after stacking, the pictures have looked green in their colors. Flat, bias, darks are integrated. Camera 40Da, also with the 70D. This picture was taken with the 70D. Even without dark, the colors are very different. All pictures taken in the same night.
My question is, why is that? This is not the case with another program, Figure 2.
greetings André
This could be due to the use of filters or some other influence that causes that in the data. APP doesn't change the raw data just like that, so it has to be in there to show up. Did you try color calibration? You can also tweak that calibration slightly to account for the effect some filters have, I can show you if you tried it with some pictures.
Hi,
I've tried a lot, including different types of filters. I changed the camera settings because I thought it was because of it, but to no avail.
I deleted version 1.075 and reinstalled the 1.070. Now it works like the years before and the colors are right.
Now the question is what was wrong there.
Doesn't the program normally start so that the settings are on standard?
greetings André
Yes it does, but these have changed a bit during versions. I would advice to use 1.079 as that also has many bug fixes. If you have the same cast, I can have a look at it if you want to share the data and explain it better.
