The Orion 27194 Skyquest XT8 Dobsonian telescope is a one of the most popular telescope models around. For the price, it’s a massive item, weighing an impressive 41lb, with a 1200mm (46.5 inch), focal length, and a 203mm (8 inch) diameter mirror. This Classic Dobsonian telescope is a really easy to use design, consisting of a tube with eyepiece near the open end, (like a Reflector telescope), but instead of a potentially complicated Equatorial mount and tripod, the telescope is attached to a sturdy base plate.
