Sky-Watcher 8" Classic Dobsonian Telescope
Dobsonian telescopes are such a great deal when it comes to light-gathering versus cost! Simple to use, the Sky-Watcher 8" Classic Dobsonian is perfect for the beginner, an older child, a classroom, or frankly, anyone who wants a straightforward telescope with 8" of aperture for views similar to that of telescopes costing hundreds of dollars more!)
This Skywatcher 8" Dobsonian telescope is called a "Classic" because the telescope portion is a traditional Newtonian reflector with a solid-style tube. This is the same style telescope John Dobson used when he created his inexpensive and easy-to-build Dobsonian.
The lazy-Susan style base is what makes a Dobsonian a Dobsonian! The circular base rotates 360 degrees and the OTA sits on a cradle that allows the telescope to easily move up and down as well. With this combination you can look in pretty much any direction, from horizon to horizon.
