2. List of telescope types - Wikipedia

   en.wikipedia.org/wiki/List_of_telescope_types

   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.

3. John Dobson (amateur astronomer) - Wikipedia

   en.wikipedia.org/wiki/John_Dobson_(amateur...

   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.

4. Dobsonian telescope - Wikipedia

   en.wikipedia.org/wiki/Dobsonian_telescope

   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 ...

   en.wikipedia.org/wiki/Obsession_Telescopes

   Obsession Telescopes builds two different styles of compact truss-style Dobsonian telescopes which can optionally be equipped with computerized positioning. [4] The primary mirrors range from 12.5 inches to 25 inches in diameter and are supplied by Optical Mechanics, Inc. (OMI) and Ostahowski Optics, while secondary ones are supplied by United ...

   en.wikipedia.org/wiki/UNCOVER-z12

   UNCOVER-z12 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) [1] during NIRCam imaging for the JWST Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization (UNCOVER) project [2] in November 2023. UNCOVER-z12 is within the Abell 2744 supercluster in the constellation Sculptor. [3]

7. Altazimuth mount - Wikipedia

   en.wikipedia.org/wiki/Altazimuth_mount

   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.
