I'm after some rings for my 10" SW Black Diamond OTA. The ones I have suit the Vixen type dovetails, but I've recently upgraded the mount and refractor dovetails to Losmandy type from ADM.
I'm aware of Parallax rings, but they seem expensive at $250. I'm after that flat 4" min flat top and bottom with 2 screw fixings instead of 1.
Other thing is size. 10" is nominal, I know. Scope is f/4.7 1200mm FL. The OTA is about 11.3" diameter. I see Parallax website has 10", 11", 11.6" etc. can they do in-between?
