A Dobsonian telescope is a Newtonian telescope with a
low, altazimuth mounting, typically
using Teflon pads as bearings on a flat board, in which the telescope is
supported by V-shaped cuts in the side of a wooden box. Named for the Californian
"father of sidewalk astronomy" John Dobson (1915-), who advocated simplicity
in equipment, the basic Dobsonian was designed so that amateur astronomers
could easily create their own large-aperture reflecting telescope mounts in home workshops.
