Most refractor telescopes come in two parts: a mounting tripod and the telescope with a drive system. If properly set up, these types of telescopes will automatically follow the arch of the stars and planets as they move from east to west. Depending on what type of system you have, you may have to manually move the telescope unless it is equipped with electric drives on both axes.
One the most important parts in setting up a telescope mounted on a tripod is that the tripod head has to be perfectly level before attaching the telescope. This may take a little time, but it's worth it. Some telescopes come with a bubble level attached to the tripod. If not, a small level can be purchased at your local hardware store.

A Dozen Telescope Observing Tips For Beginners

Observe away from buildings, pavement or large objects that absorb heat by day and release it at night. When these objects release heat at night, they create air currents (heat mirages) which degrade image quality in your telescope. This is why observing from a terrace or top of a building is not a good idea. The best locations are open, grass covered areas.
