Overview ：
The 20-60X80ED Spotting Scope combines a high-transmission optical path with a nitrogen-filled  to deliver reliable imaging performance at low light and in unforgiving weather conditions. At the core of the  fully multi-coated optics, including BAK4 prisms and an extra-low dispersion (ED) glass objective that minimizes chromatic aberration and maximizes light gathering.Multiple layers of Celestron's proprietary XLT coating on each lens preserve brightness and transmit contrast-rich images to the eyepiece.This spotting scope includes a 20-60x eyepiece that is ideal for intermediate- to long-range glassing.The broad magnification range, comfortable 20mm eye relief, and twist-up rubber eyecup make this zoom eyepiece well suited for long-duration observations.The scope's standard 1.25" eyepiece mount will accept most astronomy eyepieces, which enables a near-infinite number of optical configurations.
