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 ...
The 24-inch (610 mm) Dobsonian telescope brought by the Sidewalk Astronomers was unconventional, because most telescopes at such meetings tended to be smaller, on equatorial mounts, and designed for astrophotography rather than optical viewing. Surprisingly (and controversially at the time) Dobson's telescope tied in first prize for best optics.
Some telescopes are classified by the task they perform; for example Solar telescopes are all designs that look at the Sun, Dobsonian telescopes are designed to be low cost and portable, Aerial telescopes overcame the optical shortcomings of 17th-century objective lenses, [1] etc.
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.
Obsession Telescopes is an American optical telescope company that specializes in the production of Dobsonian telescopes. [1] The company was founded in 1989 by David Kriege, and is based in Lake Mills, Wisconsin [ 2 ] and operates globally.
A Newtonian telescope on a simple Dobsonian mount. An altazimuth mount or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument.
Its two domes house the main instruments (a Meade 16-inch LX-200 and a Celestron C-14) and a roll-off structure houses a 17-inch Dobsonian. The Grand Rapids Amateur Astronomical Association takes pride in its James C. Veen Observatory near Lowell, Michigan, a multifaceted educational and research facility named after the co-founder and first ...
Primary lens: The objective of a refracting telescope. Primary mirror: The objective of a reflecting telescope. Corrector plate: A full aperture negative lens placed before a primary mirror designed to correct the optical aberrations of the mirror. Schmidt corrector plate: An aspheric-shaped corrector plate used in the Schmidt telescope.
