About this item
Invented in the 70's the Telrad Reflex Sight was the first of a new kind of finder available to amateur astronomers. Outfitted with a generous 2.5x1.4" viewing window it provides a wide unmagnified true view of the sky — unlike conventional finder scopes that offer limited fields of view presented upside-down and backwards. Three concentric rings — spaced at 4°, 2°, and 0.5° — provides an easy point of reference for locating objects and quick navigation when manually star-hopping. An easy-to-use, infinitely-adjustable rheostat enables precise brightness control so users won't hurt their night-adjusted vision. A mounting base is included, and the sight easily detaches from it for storage or to move it to another OTA with a separate mounting base already attached without requiring it to be re-centered with the OTA.
