Hello,
This is a new question I hope. If discussed before, let me know
I try to load a fit image from my las session (SBIG ST8300C) in pixinsight and a new software named siril.
Same result the image is considered as monochrome. On the advice of siril developper I tried to lod it with debayerization with the bayer pattern set in siril to BGGR.
It works I obtain 3 images but the combination of the 3 images gives a RGB uggly one with a violet foreground.
Now, I don't know what to do more.

Any idea ?

Color-wise looks fine in KStars, but it is out of focus (and/or guide issues). I tried it under PixInsight with Debayer tool and got the same result (but I had to unlink RGB channels in the ScreenTransferFuction).

I guess it is guide issues because I had a HFR between 1.7 and 2. But I must admit it I don't know what is a good value for HFR.
