Orion Illuminated 20mm Centering Eyepiece

Features an LED red illuminated crosshair pattern when looking thru the eyepiece that aids in polar alignment of a telescope on an equatorial mount AND in alignment of a telescope's finder scope. It will also precisely aid in aligning a computerized go-to telescope!  A large 70 degree field of view, 20 mm eyepiece assures an easy object acquisition.  A rotating battery operated knob on the side of eyepiece turns on/off the illuminated crosshairs and the brightness is controlled by turning the knurled knob, similar to a dimmer switch.  The eyepiece is in perfect working order and in excellent cosmetic condition.  Included is the original Orion carton, 2 protective eyepiece endcaps, installed LR button cellbatteries, and an instruction manual.  I will pay shipping costs to CONUS only and ask that you pay with PayPal F&F if at all possible.
