The Orion 20mm Illuminated Centering Eyepiece can be used for 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. 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. 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.
