How to Use an Equatorial Telescope Mount
When you use your telescope to watch the night sky, there may be some objects you want to keep track of every night as they move across the sky. The best way to do this is to use an equatorial mount. This type of telescope mount is parallel in line with Earth's axis of rotation, so that you can move the telescope along the same line as the motion of the object in question.
