Looking for a 2nd hand 45 degree premium erecting prism diagonal in the 1.25 format. It is my understanding that these units are identical but badged differently and thus the identical unit is sold by both Orion and William Optics. I would be happy with either.
Please send me a message if you have one made by either manufacturer which you would like to sell.
If this will help the situation in finding a 2nd hand 45 degree diagonal - I am simply looking for a 45' diagonal - irrespective of brand/manufacturer PROVIDED - it features a brass compression ring in the eyepiece coupling.
There are many models of 45' diagonal which feature a simple thumb screw but I want to avoid these models as I hate accidently marking my eyepieces.
Consequently, if you have ANY brand of 45 degree diagonal which features a compression ring and not simply a thumb-screw then I would be happy to buy it!
