Howdy,

I need to know the external diameter, and the diameter of the secondary mirror holder, of a Celestron C8 (ideally a CPC-800) so I can have a bahtinov mask cut.

I don't have the scope with me at present, so I can't measure it myself.

I'd be grateful if someone could measure their scope and post the numbers here.

Thanks in advance,

DT

Dave, I believe the hyperstar versions have a larger secondary assembly, so it depends on which type you've got.
