Description
Overview
Designed and built for beginners, the Celestron ExploraScope 80AZ 80mm f/11 Alt-Az Refractor Telescope offers a complete setup for viewing the Moon, planets, meteor showers, and bright deep-sky objects. The optics are fully coated with anti-reflection coatings to reduce light loss and produce brighter and clearer images with improved contrast.
The scope features a manual alt-azimuth mount with an altitude adjustment rod that allows users to track objects as they move across the night sky. Two eyepieces are included to produce 45x and 225x, with a 3x Barlow lens that effectively triples the magnification of each eyepiece. A 90° diagonal is also provided to put the user in a more comfortable viewing position, and it has an erector prism to correct the image orientation horizontally and vertically to enable the scope to be used for terrestrial viewing as well. Its adjustable aluminum tripod provides a stable observation platform, and its adjustable height from 31 to 52″ allows for comfortable viewing by most users.
