iTelescope Basics- The Mount


A good telescope mount is the bedrock upon which any decent observatory setup is built.
A telescope mount does two things: one, it holds our telescope securely; and two, it allows you to move the telescope so that it can be pointed precisely at the objects in the night sky you want to observe.
Most of the telescopes at iTelescope are mounted on the (German) Equatorial mount. An equatorial mount is a telescope mount that rotates the optical tube of a telescope around two axes in the same plane. The word is derived from its resemblance to our equator, which this system approximates due to the axial rotation it imparts about a base meridian.
The (German) Equatorial mount has two axis of movement. Both axis are required to point to a specific object of interest in the sky. Once the telescope has moved into position so that the telescope is centered on the object, only one axis, the – Right Ascension Axis – is required to move as it compensates for the movement of the earth (polar axis)
