Orion 20mm Illuminated Centering Eyepiece, 1.25", with 70 Degree Angle of View

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.
