Orion 20 mm Illuminated Centering Eyepiece
Orion 20 mm Illuminated Centering Eyepiece
You'll never be left in the dark with the Orion 20 mm Illuminated Centering Telescope Eyepiece! Whether acquiring and centering stars for GoTo system alignment, or lining up guide stars for astrophotography, the 20 mm Illuminated Centering Telescope Eyepiece will quickly become one of your most useful imaging tools.
The 20mm Illuminated Centering Eyepiece offers a relatively long 20 mm focal length and a wide 70° 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 to center objects.
This eyepiece is fully multi-coated (all air-to-glass surfaces) with anti-reflection coatings for bright, crisp views. It features a great 16 mm eye relief and the barrel is threaded for 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 AG5/309/393 button cell alkaline batteries or batteries of equivalent size and voltage (not included).
