The ability to gather light to the telescope is dependent on the Aperture. It is a larger primary optics. Then on the optical quality, contrast, and collimation.

The focus property of the telescope is dependent on the collimation, optical quality of the eyepiece and focusing mechanism.

The following characteristic are required to mount a telescope at the minimum level. They are stability, rigidity, and smooth motions.
