Don't ask how (!!??) but I've ended up with a spare 2" Meade SC mirror diagonal... I'll sell for what what I paid $75 +pp
Will fit all the SC models, Celestron and Meade.
I can't remember seeing a model #, but I'll double check tonight and upload a photo. It's a "standard" Meade SC fitting UHCT 2" mirror diagonal with 1 1/4" reducer.
Just checked: As received form the US. it's a Meade #937 2" mirror diagonal originally for the DS series telescopes. It has the SC fittings at one end and 2" adaptors for 1 1/4" and small japanese (0.95"?) at the other: in original box and documentation.
I should have opened the box properly. It IS a Model # 937, 2" Meade DS diagonal BUT it's for a 2" eyepiece holder NOT the SCT thread. Sorry for the screw up.
