Meade 12mm Illuminated Reticule Features:
The illuminator LED has an expected life of 10,000 hours of use if operated with the correct 3-volt input.
The eyepiece has a dual crosshair reticle. The top of the eyepiece rotates to focus the crosshairs sharply to match your eyesight.
The illuminator can not be plugged into the 9 to 12 volt auxiliary power outputs on other brand telescopes or into the 12 volt auxiliary output on the base of the Meade LX50. Such misuse will burn out the 3 volt LED of the illuminator and is not covered by warranty.
