Polar Alignment – Even the most casual observer knows that the Sun and stars move across the sky. These objects appear to move because the Earth rotates on its axis every day. In order for you to observe an object for any length of time, your telescope must track the sky in sync with the Earth’s rotation. This document will help you get good polar alignment with your telescope. [polar-alignment.pdf]
