DOBSONIANS
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
easy 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 slow motion controls. Tube material: Aluminium
