=== Open fork mount === [[Image:Warszawskie Obserwatorium Południowe Teleskop.jpg|250 px|thumb|left|Open fork mount]] The '''Open Fork''' mount has a ''Fork'' attached to a right ascension axis at its base. The telescope is attached to two pivot points at the other end of the fork so it can swing in declination. Most modern mass-produced [[catadioptric]] reflecting telescopes (200 mm or larger diameter) tend to be of this type. The mount resembles an [[Altazimuth mount]], but with the azimuth axis tilted and lined up to match earth rotation axis with a piece of hardware usually called a "wedge".<ref>{{cite web | url = http://www.universetoday.com/guide-to-space/telescopes/telescope-mount/ | title = Telescope Mount | publisher = [[Universe Today]]}}</ref> Many mid-size professional telescopes also have ''equatorial forks'', these are usually in range of 0.5-2.0 meter diameter.
