: The foundation that supports the telescope and allows it to track the movement of the night sky.

: A mechanism, such as a rack and pinion focuser , used to adjust the distance between the eyepiece and objective to sharpen the image. Astrophotography Equipment | Ultimate Beginners Guide

An astronomical telescope's performance is primarily defined by two factors: and resolution , both of which depend on the size of the objective lens or mirror (aperture).

: The main optical element that collects light. Larger apertures allow for the observation of fainter objects.

: The lens you look through, which magnifies the image formed by the objective. Most telescopes use interchangeable eyepieces with different focal lengths to vary magnification.
