This is a mint condition (never used) TeleVue 2" Diagonal machined out of solid aluminium with a 1/20th wave mirror. Set-screw type. I am the original owner. This was purchased as part of a TV Rich Field Kit. TelVue didn't put their name on this model, but the photo below shows their original brochure. The Celestron C-8, Meade 2080 adapter that came with the kit is included.
