Equatorial Mount

A telescope mount designed for astronomical use. It aligns the axis of rotation of a telescope with the axis of the Earth, allowing the scope to follow the seemingly curved paths taken by the stars and planets. When equipped with a motor drive, it automatically tracks celestial objects without the need for constant manual corrections, as is the case with an altazimuth or Dobsonian mount. This is particularly important at high magnification, where objects drift across the field of an unmoving scope in a minute or less. Usually supplied with setting circles that help locate objects by their right ascension and declination coordinates. Convenient for visual observing and essential for astrophotography. Two types are commonly available with commercially-made amateur telescopes -- the German equatorial and the fork mount.
