Anyone know if a right angle diagonal and eyepiece adaptor is available for purchase.
An ordinary 1.25" 90 can fit over my polar scope wnen the screwed in polar scope lens is removed, but the focal lenght is incorrect when the eyepiece is plcased at the end of the diagonal.
I did however find that an acromat lens (of the correct FL)placed at the end of the diagonal can work (when duct taped in place).
I'd rather purchase a correctly fitting unit.

Nope, never heard of such a thing. Not a bad idea, though.

Not specifically but how about a right angled camers viewfinder?
sounds like you should register the idea quick before the sharks produce it and start an action if you make your own. Make a mock up immediately, they hate 'prior art'
