Design

The M49 is a fixed 20-power telescope with an eyepiece focus. It has a field of view of 2 degrees and an exit pupil diameter of 0.108 inches. The M49 is an erect image instrument that is magnified by the lenses in the eyepiece. [3]

The M49 does not have an adjustable sunshade; however, the front end of the body tube extends approximately three-quarters of an inch beyond the objective providing a permanent sunshade.

The telescope is focused by turning the knurled focusing sleeve. [4]
