straight thru scope A spotting scope is a telescope with a large objective lens, which produces a bright, upright image of great clarity and detail.  Spotting scopes typically feature usable magnifications between 20x and 60x in normal daylight conditions.  They may have a rubber-armored design and can be mounted to a tripod.  Most spotting scopes are ergonomically designed with a knob for focus control.  They include either a single eyepiece with variable zoom or several eyepieces with different magnification powers.  Light gathered is determined by the objective lens diameter, which is usually between 50 mm and 80 mm.

angled spotting scope The two main types of spotting scope are "straight-through" and "angled."  On a straight-through scope, the eyepiece and the body of the scope are on the same axis, whereas on an angled scope, the eyepiece is angled about 45 degrees from the scope body.  Spotting scopes with a magnification range lying between 20x and 30x are generally favored for bird watching and hunting, while scopes with higher magnification ranges are preferred by astronomers.  Some spotting scopes can be used as both visual and photographic instruments.  With appropriate adapters, scopes from certain manufacturers can serve as telephoto lenses for 35 mm SLR cameras and digital SLR cameras.
