A spotting scope is a small portable high-power telescope with added optics to present an erect image, optimized for the observation of terrestrial objects. They are used for various outdoor activities such as birdwatching and other naturalist activities, for hunting and target shooting to verify a marksman’s shot placements, for tactical ranging and surveillance, and for any other application that requires more magnification than a pair of binoculars, typically on the order of 20× to 60×.
The light-gathering power and resolution of a spotting scope are determined by the diameter of the objective lens, typically between 50 and 80 mm (2.0 and 3.1 in). The larger the objective, the more massive and expensive the telescope.
The optical assembly has a small refracting objective lens, an image erecting system that uses either image erecting relay lenses or prisms (Porro prisms or roof prisms), and an eyepiece that is usually removable and interchangeable to give different magnifications. Other telescope designs are used such as Schmidt and Maksutov optical assemblies. They may have a ruggedized design, amounting for attaching to a tripod, and an ergonomically designed and located knob for focus control.
