Hey Guys I need a source for porroprisms. The type you put in your epiece holder and put your eyepiece in the other end. I'm trying to work out a binoscope project and any help would be appreciated. Thanks, Randy

Tele Vue's porro prism assembly includes a brass compression ring and can be purchased from any Tele Vue dealer -- including Anacortes.

Astro-Physics also has a porro assembly (which may be identical to the TV unit).

Not sure if Vixen is still making their porro assembly (perhaps the TV and A-P units are sourced from Vixen -- I know they *used* to be). Orion B&T may actually still have a few -- you might give them a call.

Porro prism assemblies in the 1.25-inch format are indeed becoming less common and harder to find. They can still be found on the 2nd-hand market, for sure -- most of these being Vixen-made.

Best wishes.
