Telrad Finder Sight Red / Green Switchable with Mounting Base

Color: Red and Green NEW: New model with user-selectable red or green illumination. There is a new toggle switch on the front of the Telrad on one side that lets you easily select the illumination color you want for the best contrast against the sky background. The standard Telrad only as red illumination. To see objects through a telescope it must be pointed to exactly the right spot. The Telrad is a sight for pointing telescopes to that "right spot." Through a Telrad you see the sky the way the star charts show it. Not a small upside-down and magnified portion of it, but the "real sky" with three lighted target rings set against it. The large ring is 4 degrees across. It outlines the area covered by a finder scope. The center ring is 2 degrees in diameter. The small ring is 0.5 degrees across and outlines the area seen in the telescope. Select an object on the chart and note its position among the visible stars. Then set the Telrad rings on that spot in the sky. A quick rough setting will put the object in the field of a finder scope. With no finder, or a faint object that won't show, use a more careful setting to put the object in the field of the telescope. The Telrad is 8 inches long, weighs a mere 11 ounces and mounts on almost any telescope or spotting scope without drilling holes. It unlocks from its base for separate storage. Runs on two AA batteries (not included). The Telrad Sight has also found wide adoption in the stage lighting industry. It works very well as a spot light sighting device for professional concert and stage spot light operators.
