Stellarvue Crosshair IlluminatorThe Stellarvue EI2 Crosshair Reticle Illuminator:
Use this illuminator to make the crosshair reticle in your finderscope eyepiece more visible at night. This illuminator will screw into any reticle eyepiece (having the provision for illumination) to provide you with a variable brightness red illumination for the crosshair.
You can adjust the brightness to suit your preference, while preserving your night vision at the same time by turning the knurled aluminum brightness knob. You can also turn the illumination off.
It uses two standard GPA76 batteries. The batteries are included.
Excellent illuminator and wonderfull services from OPT

Red Light Wonder
Very easy to use. Easy adjustability for brightness.
Seems well built, but
Switch is not great. To ensure it stays off I’ve loosened the connection of the battery compartment. It will work fine just for storage care is required.
good product, fair price fast delivery -- as always
