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 OTA, or telescope tube, has a 1200mm focal length and is fitted with a 2" focuser that can accept both 2" and 1.25" eyepieces due to the inclusion of a 2" to 1.25" adapter. The Sky-Watcher 8" Dobsonian also comes with a full-sized 9X50 optical finder to help you locate objects in the night sky and center them in your eyepiece.
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. This model also includes a tension control handle to adjust the drag when using accessories of different weights so the tube stays put when you look through the eyepiece.
You will receive two 1.25" eyepieces with your new telescope; a 10mm and a 25mm, which will give you 120X and 48X, respectively.
