- Orion 20mm Illuminated Centering Telescope Eyepiece
You'll never be left in the dark with the Orion 20mm Illuminated Centering Telescope Eyepiece. Whether you're acquiring and centering stars for GoTo system alignment, lining up guide stars and/or target objects for astrophotography, or just testing the accuracy of your tracking system, the 20mm Illuminated Centering Telescope Eyepiece will quickly become one of your most trusted and useful imaging tools.
In comparison to most standard low-focal length illuminated reticle telescope eyepieces, the 20mm Illuminated Centering Telescope Eyepiece 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.
The illuminator is powered by two AG9 button cell alkaline batteries (included). The Illuminated Centering Eyepiece weighs 8 ounces.
