Description
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.Performance Wide unmagnified field of viewGenerous 2.5x1.4" viewing windowLong eye reliefZero parallaxProvides uncluttered, correct 'real sky' view for quick manual sighting of known objects like planets, stars, clusters, and galaxiesReticle Red illumination makes reticle clearly visible without affecting night-adjusted visionThree concentric circles set at 4 , 2 , and 0.5 to help 'star hopping'Infinitely-adjustable rheostat allows for precise illumination controlUse and Handling Quick detachment from mounting base enables it to be removed and installed quickly without re-calibrationRuns on two user-supplied AA batteriesWeight: 9 ounces without mount
