Piggy backing on a C6

[iancandler]

I seem to be having trouble finding a rail so I can piggy back my ZS66 on the C6, I mean the OTA has the two rear cell screws 1.75" apart for accessory rails but no front screw holes that match and its that odd length.

Most solutions I see are for the C8, meaning the rail is longer and Im not sure the radius blocks will fit properly.

Has anyone else come up with a solution that doesnt involve a side-by-side bar or putting the whole thing on rings, cos I cant/dont want to go that way

I dont even want to mount guide rings, I have a wide enough field with the scope and my guide cam to get a half decent guide star.
