The problem is that, PixInsight open cr2 raw file unrotated, and i must to rotate all.
Pi can't write cr2 extension, and i must to give extension xisf and is ok. But this modification don't alterate image information?
If i rotate all image with xisf extension, then image integration, then i made superbias file, and in final image,  file is demage image.
I must to debayer? In Pix with preprocesing i can made an superbias file from masterbias. But is gry, and when i made with image integration an superbias file is color.

Please advice me, how i can made an good superbias. I have made superbias like in imageintegration image example.
Please escuse my bad English.

Thankyou.

Hi Biosif!

I have noticed your settings in ImageIntegration

In the section PixelRejection (1)
> Rejection algorithm: for a large number of subs (more than 20) Linear Fit Clipping is recommended
> Normalization: No normalization is recommended


Best regards!
