1. Small telescope

   A small telescope is generally considered by professional astronomers to be any reflecting telescope with a primary mirror that is less than 2 metres (80 in) in diameter. By amateur standards, a small telescope can have a primary mirror/aperture less than 6–10 inches (150–250 mm) in diameter. Little if any professional-level research is performed with refracting telescopes in the modern era of astronomy. Small telescopes dominate astronomical research in the fields of asteroid/comet discovery/observation, variable star photometry, supernova/nova discovery, and colorimetry/polarimetry of the Solar System's planets. Because of their limited light-gathering capability, small telescopes are usually not well-suited to spectroscopy, although some useful spectroscopic work can be performed with reflecting telescopes with a primary mirror as small as 14 inches (360 mm) when equipped with the increasingly sophisticated CCD imaging and spectroscopic instrumentation that has become available to amateur astronomers in the 21st century. Most telescopes within the field of amateur astronomy are considered to be small, ranging in general from 2-inch (50 mm) achromatic refracting types, to reflecting telescopes featuring primary mirrors up to 36 inches (910 mm) or more in diameter. Most small telescopes are dedicated to visual observation, although many are used for astrophotography or to gather scientific data. The range of amateur astronomers' telescopes is wide, with numerous types and designs. Refracting designs include achromatic and apochromatic types. Some reflecting types are Newtonian, Schmidt–Cassegrain, Maksutov-Cassegrain, and Maksutov-Newtonian. Even sophisticated designs, such as the Ritchey–Chrétien and (corrected) Dall–Kirkham, which have traditionally been the preserve of large professional-grade instruments, have become available to amateurs.

Examples of small telescope in a Sentence

1. Jamie Cooper in Lincolnshire:

   I managed to photograph the comet approaching on Sunday evening through a small telescope, the comet has a similar orbit to the Great Comet of 1844, leading to speculation on whether C/2019 Y4 is a fragment of the same parent body.
