12.5mm Illuminated Reticule Eyepiece

Illuminated reticule eyepieces improve manual guiding performance, and aid in polar alignment, two critical points when it comes to capturing pin-point star images during long-exposures.

The thin double crosshair reticule illuminates via a cordless variable-brightness red LED illuminator. A built-in helical focus allows the user to bring the reticule into focus.

By correctly aligning the crosshairs with the RA and DEC motion, you can greatly simplify manual guiding.
