Description
You'll never be left in the dark with the Orion 20mm Illuminated Centering Eyepiece (ICE). Whether you're acquiring and centering stars for GoTo system alignment, lining up guide stars and/or target objects for astro-imaging, or justtesting 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 length and a wide 70-degree apparent field-of-view, making it easier to locate desirable targets for alignment or guiding. Thisvirtually 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 switchdoubles as a dimmer allowing you to adjust cross-hair brightness to the desired level.The illuminator is powered by two AG5 button cell alkaline batteries (included) and weighs in at 8 oz. One-year limited warranty.
