Tele Vue Starbeam 1x39 Finderscope with Tele Vue Quick Release Base

The unique design of the Tele Vue Starbeam 1x39 Finderscope offers two modes of use: straight-through line-of-sight, or 90° angled viewing when the optical tube assembly (OTA) is pointed high overhead at or near the zenith. A mirror flips up for a more comfortable viewing angle when the tube is pointed up, and simply folds down when the OTA is pointed more parallel to the ground.
