Product description

• ED80 80mm f/6 Carbon Fiber Refractor Telescope (OTA only) The ED80 80mm f/6 Carbon Fiber Refractor Telescope from Explore Scientific is a versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope, as a large finderscope mounted to a larger scope such as a Dobsonian, or set up on a dual-mount rig for astrophotography/astroimaging. Using Extra-low Dispersion (ED) glass in a triplet lens configuration, with fully multicoated optics, creates images that are clear and bright without distortion across the entire field of view, with true color rendition.Its carbon fiber optical tube is temperature-resistant with reduced expansion/contraction due to temperature changes that can affect the fine focusing abilities under extreme fluctuations. The carbon fiber is durable while reducing the overall weight. A 2" 90° star diagonal is included for comfortable viewing and aids in viewing objects approaching the zenith.

• Exos-2GT Computerized German Equatorial Mount with Tripod Built for use by beginners or experienced amateurs, Bresser's Exos-2GT Computerized German Equatorial Mount with Tripod helps take the guess-work out of astronomy and gets you observing faster by combining an EQ mount and stainless steel tripod with a 100,000+ database computer guidance system and dual-axis motors. The mount is designed for refractors up to 152mm aperture and reflectors of up to 203mm, with a maximum payload capacity of 29 pounds. It features a GP-level dovetail saddle for compatible OTAs and an integrated bubble level to assist in set-up.The SkyTracker kit includes the hand controller unit, and right ascension and declination motors. Its hand controller 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.
