The Keuffel and Esser classic 71-2062 Line of Sight telescope provides precise optical reference lines as its optical axis exactly matches its mechanical axis. Focus is from 7" from the front of the barrel to infinity, with a magnification of 23X at close focus to 35X at infinity. With its fully coated optics, it offers a bright image with its 38mm aperture, yet offers the ability to resolve 3.5 seconds of arc! The reticle is an all-purpose Cross pattern with double lines at the bottom and left, and single lines at the top and right. This telescope is mated to a 71-1241 Combination Auto-Collimation, Projection and Right-Angle eyepiece. This unit offers a 90 degree eyepiece for tight situations, but it is the only way to keep auto-collimation capability in the 2062 with a right-angle eyepiece. This includes a Lightglo LED illuminator, and will be fully serviced and Calibrated to meet or exceed new factory specifications
