Telescopes can be classified by optical design or mechanical design/construction. Telescopes can also be classified by where they are placed, such as space telescopes. One major determining factor is type of light, or particle being observed including devices referred to as "telescopes" that do not form an image or use optics.
Some sidewalk "pitch men" charged the public to view astronomical objects through their telescope but other astronomers allow people to view for free. [6] [10] In more recent years sidewalk astronomy has come to be more associated with altruistic individuals or groups offering views of the nighttime sky as a free public educational service. [11]

The near-infrared can be collected much like visible light; however, in the far-infrared and submillimetre range, telescopes can operate more like a radio telescope. For example, the James Clerk Maxwell Telescope observes from wavelengths from 3 μm (0.003 mm) to 2000 μm (2 mm), but uses a parabolic aluminum antenna. [20]
