Paul,
if your osc camera doesn't appear in the list you will probably need to select a generic one from the top of the list - there are 4 possible bayer patterns:
RGGB
BGGR
GBRG
GRBG
This website is all about the verifying the bayer pattern for the QHY8 but I'm sure the methodology will work for any camera:
