Seestar Bayer Pattern

saguaro

The FITs header lists the Bayer pattern as GRBG. However, other users report the Bayer pattern to be BGGR or RGGB, for example [https://bbs.astronomy-imaging-camera.com/d/12664-asi462mc-bayer-code](https://). Which is the correct Bayer Pattern ?

It's GRBG

GRBG when you read the FITS from top to bottom, but that gives you an upside down image.
BGGR when you read the FITS from bottom to top.

Depends how your post-processing software handles this. In Siril, if you untick the “force top to bottom” option then use BGGR. With that option ticked, use GRBG.
