Sky-Watcher 114 mm EQ1 reflector (upper right) with Tasco refractor. Sky-Watcher is a commercial distribution company established in 1999 by the Synta Technology Corporation of Taiwan (Synta Taiwan). It markets telescopes and astronomy equipment, such as mounts and eyepieces, aimed at the amateur astronomy market.
A Dobsonian telescope on display at Stellafane in the early 1980s. 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 ...
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.
Their first telescopes (4.5" (114 mm) -Newtonians) were distributed by Celestron and Tasco. In 1993, the first refracting telescopes were produced. In 1999, the brand Sky-Watcher was established by Synta Taiwan to sell optics produced by Suzhou Synta.
They designated this series as Ultra Compact (UC), referring to their former one as 'Classic.' From 2009-2012 their telescopes ranged from USD 3000 for a 12.5 inch telescope, up to USD 12–15,000 for a 25-inch telescope. [8] [9] The company manufactured a limited number of 30-inch and 36-inch telescopes. [10]
The term "Dobsonian" is considered objectionable by some purists since the Dobsonian telescopes are just Newtonian reflectors with a simplified mechanical design. Normally, proper names for telescope designs are associated with the optics (Cassegrain, Maksutov, Ritchey-Chretien etc.) and not with with the way in which the optics are mounted.
Watcher Entertainment has drawn millions of fans for their unscripted and comedic videos on YouTube — and now the studio’s three creators have drawn the ire of a significant number of them. On ...
Ever since Galileo Galilei adapted a Dutch invention for astronomical use, astronomical telescope making has been an evolving discipline. Many astronomers after the time of Galileo built their own telescopes out of necessity, but the advent of amateurs in the field building telescopes for their own enjoyment and education seems to have come into prominence in the 20th century.
