It's that easy to locate object after object, so many more in an evening than you could ever find before.
Top Features-
- Large Dobsonian reflector telescope with 8" aperture allows you to see faint deep-sky objects such as nebulas and galaxies, in addition to fantastic views of the Moon and planets
- Locating those faint deep-sky objects is simple with the IntelliScope Computerized Object Locator - it includes more than 14,000 objects in its database, and points you right to each one
- Select the object you wish to view from the IntelliScope database, then simply follow the directional arrows displayed on the hand controller by moving the telescope until the object is right in the eyepiece field of view - it's easy!
- The ultra-stable Dobsonian telescope base keeps the reflector optical tube perfectly balanced for easy point-and-view use
- A precise Crayford focuser allows use of larger format 2" telescope eyepieces - the bright, wide-field view of the Andromeda galaxy in a low power 2" eyepiece is jaw-dropping!
