Orion 20mm Sirius Plossl 1.25" Eyepiece - 08733

SKU: ORI-08733

The Orion Sirius Plossl eyepieces are Orions best-selling line of telescope eyepieces featuring tremendous quality at an affordable price. This 20mm Orion Sirius Plossl telescope eyepiece has a wide 52 degree apparent field of view enabling extremely sharp images of impressively high contrast. This eyepiece is ideal for all types of telescopes including refractors, reflectors and catadioptric. The 4 element design of the Sirius Plossl eyepiece is the standard to which all other telescope eyepieces are judged. 

For excellent light transmission and bright views, the Sirius Plossl optical system is multi-coated. For durability and precision fit, the lenses are mounted in black-anodized aluminum housings with a 1.25” diameter chrome-plated brass barrel. In order to accept standard telescope filters the barrel is internally threaded. The eyepiece features a built-in rubber eyeguard that serves to enhance viewing by helping block out ambient light and position the eye. In addition, this 20mm Orion Sirius Plossl Eyepiece excels for moderately low power scanning of open star clusters and viewing of larger galaxies and extended nebulas.
