The ED102 102mm f/7 Essential Apochromatic Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multi-coated optics. This combination of glass, lens system, and coatings eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. With its fast f/7 focal ratio, this scope is not only easy to transport and set up, when used with the included GoTo mount it is ideally suited for astrophotography or imaging of the Moon, planets, bright deep-sky objects, or wide-field photos.
To guide and control the OTA, Explore Scientific includes Bresser's Exos-2GT computerized German equatorial mount and a tripod that helps take the guess-work out of astronomy and gets you observing faster. Controlling the mount is the SkyTracker hand controller. It has more than 100,000 objects with the ability for users to input custom coordinates and favorites. With a slew speed of 2°/second and nine tracking speeds the SkyTracker can accurately keep near and deep sky objects such as the Moon, planets, galaxies and nebulae centered in your eyepiece for long exposure imaging and astrophotography or prolonged observation sessions.
The tripod is built with large 2" diameter stainless steel legs and tight tolerances to reduce vibration for clearer viewing. A center stabilizer bar pulls the accessory tray up to lock the legs in place adding further rigidity and vibration reduction. It is adjustable from 29 to 49" to accommodate a wide range of users and features large thumbscrews for tool-free adjustment in the field. An adjustable plastic tray is also included with the tripod to keep eyepieces, flashlights, and other accessories safe and at the ready.
