You'll never be left in the dark with the Orion 20mm Illuminated Centering Eyepiece (ICE). Whether you're acquiring and centerign
stars for GoTo system alignment, lining up guide stars and/or target objects for astro-imaging, or just testing the accuracy of
your tracking system, the ICE will quickly become one of your most trusted and useful imaging tools.

In comparison to most standard low-focal length illuminated reticle eyepieces, the ICE offers a relatively long 20mm focal lenght
and a wide 70-degree apparent field-of-view, making it easier to locate desirable targets for alignment or guiding. This virtually
eliminates the need for swapping out high-power illuminated reticles with lower power eyepieces in order to center objects.

The Illuminated Centering Eyepiece is fully multi-coated (all air-to-glass surfaces) with anti-reflection coatings for bright,
crisp views. It features a great 16mm eye relief and the barrel is threaded for Orion 1.25" filters. The illuminator switch
doubles as a "dimmer" allowing you to adjust cross-hair brightness to the desired level.

The illuminator is powered by two LR-44 batteries (included) and weighs in at 8 oz. One-year limited warranty.
