It is a very simple design for amateur telescope makers that used a pivot point and an inclined plane that made a very low profile "table". This type of mount has been a popular retrofit for altazimuth mounted telescopes, such as the common Dobsonian telescope type, adding equatorial tracking for high magnification work and astrophotography.
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers. Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large ...
This gives equatorial tracking to anything sitting on the platform, from small cameras up to entire observatory buildings. These platforms are often used with altazimuth mounted amateur astronomical telescopes, such as the common Dobsonian telescope type, to overcome that type of mount's inability to track the night sky.
In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. [5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. [6]
Volunteers built modern digital tracking and driving systems to steer the 60- and 100-inch telescopes. They lubricate the telescopes and operate them on public viewing nights.
