Circle V 90° Prism Diagonal?

[Davesellars]

Anyone know anything about the Circle V?

Looking at possibly purchasing one used from ENS...  It states made in Japan so I assume that the quality is good...  But I can't find any information about these if they are any good or I should just save up more and get a Baader T2 prism diagonal in a couple of months when funds allow...  It's a bit worrying that ENS don't provide any photos of the actual inside / condition of the prism itself...  I've never had any dealings with them before but they never really add details by the looks of it...

Circle V is Vixen.

As for the prism, it'll depend on age.  Some old ones are uncoated or have only MgF2 coatings.

Brand new stuff from Japan has multi-coatings on the outer surfaces.

Thanks Don. In that case it has far too many unknown factors to take the risk at that price.  I'll use the cheap 45 degree prism with the binoviewers for the moment until I can afford a Baader T2 prism.
