Dobsonian Telescopes
The Dobsonian telescope is a different kind of reflector scope since it is not mounted on a tripod, but a cradle that can swivel. The cradle is manipulated by hand to best locate the specific celestial objects that you are searching for. They are very easy to use and due to their large diameter, which allows it to really gather the inbound light, you can get awesome views of deep space objects.
Due to the cradle design, it is harder to attach a camera to the eyepiece, and does not have the all important electronic tracking, so is not the best astrophotography tool.
Advantages
ease of use
reasonably priced
excellent light gathering and views
Disadvantages
large and bulky
not easily adapted to camera attachments.
No electronic tracking mechanism
