In great condition with both end caps and the original box.
I got this as part of a package deal on a used telescope but I just don't need it. It doesn't have any paperwork with it so I don't know any of the specs or coating info, but it looks like a really nice diagonal. It has the brass cinch ring/compression ring instead of a set screw.
There are 2 really tiny marks (scratches or dust?) on the mirror but I have tested this diagonal on my mak and on my refractor and the diagonal performs wonderfully, the views are not affected at all.
$60.00 shipped - I prefer paypal (no extra fee).
Thanks for looking,
