The diameter of the objective is known as the aperture; it generally ranges from a handful of centimetres for tiny spotting telescopes up to one metre for the largest refractor in existence. The objective, together with the eyepiece, may have numerous parts. Modest spotting telescopes may possibly have an extra lens powering the eyepiece to erect the graphic to ensure that it doesn't surface upside-down.

Employing one particular of these scopes, you can begin by looking at the moon, move on on the planets from the solar program, and then enterprise on to the “deep sky” to look at star clusters, nebulae, and galaxies.
