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 and good day,
I try to get to a solution here - I am using Astroberry now (as an alternative to ASIAIR Pro) and got my first shots of an easy target, M42. The files are about 73MB large (with ASI about 50MB) and after trying to process them (including stretching), they are just unusable - only one channel seems to have been processed and stretched - the Red channel (the ASI is a RGGB sensor/matrix camera). A screenshot out of PI shows what I mean.
I assume, that one has to activate the option "3D Cube" in the setup of the EKOS system to get to "normal" XISF files, right? Or did I do anything else wrong?
Thanks and regards
Georg

I personally don't use Astroberry at the moment, I think it's better if you ask on their forum? You will likely get a detailed answer there. Also, what does APP show, the same?
@vincent-mod I asked Georg on the INDI forum to post here. As it happens I own an ASI2600MC too so perhaps I can help a bit.
@gnnyman Can you upload 5 of those images to https://upload.astropixelprocessor.com/ using upload1 for both username and password? Please create a directory called gnnyman_asi2600mc and put the files in there. Then I will have a look. Thanks!
Hello again,
I was so furious, that I deleted all of those files, But as soon as I have a clear sky, I shall shoot again and then I post those images as you suggested..
Thanks
Georg
@gnnyman Georg, I took these pics with our ASI2600MC last night. Does this look like what you are experiencing as well?
I took about 20 images with the ASI2600MC using NINA and the ZWO ASCOM driver but I see similar issues using Ekos (installed myself on a Raspberry Pi 4 running Ubuntu Mate so in a way very similar to your AstroBerry) and with ASIStudio on Windows (which only uses the native ZWO driver and not ASCOM).
The first couple of images only seem to have green data:
Then there is one image with a transition. Note the 'bar' at the top of the image:
Â
Then several look like this:
And then finally a few more images like the first one appear. The images were taken using a SkyWatcher Esprit 80 and a 2" L-Extreme filter but that of course doesn't matter for how the sensor works.
Hello again,Â
I have no idea, what changed, but yesterday evening, everything was fine - the files are as expected and as usual....thanks for your ongoing support!
Georg
