These instruments offer an incredible aperture-to-price ratio.
The Dobsonian mount, popularized by John Dobson in the late 1970's, is a
very simple but effective method of mounting a Newtonian Reflector,
based on the alt-azimuth principle.
Fast and east to set up, the Dobsonian mount consists of a box-type
mounting which allows the telescope to pivot in altitude, while the box
itself is rotated on a base in azimuth. The secret of the design is to
correctly balance the optical tube and to use frictional materials which
allow it to move easily when nudged but to stay in position when not.
The mount is designed to be driven by hand as opposed to motor driven or
via slow-motion controls, and as such make them more suitable for use at
low-to-medium magnifications and for deep-sky observations.
