Ever since Galileo Galilei adapted a Dutch invention for astronomical use, astronomical telescope making has been an evolving discipline. Many astronomers after the time of Galileo built their own telescopes out of necessity, but the advent of amateurs in the field building telescopes for their own enjoyment and education seems to have come into prominence in the 20th century.
In 1963, the 19-year-old Japanese amateur Kaoru Ikeya created national headlines when he discovered a comet with his homemade telescope. Itagaki was thus encouraged and bought a 15 centimetres (5.9 in) telescope and, after completing highschool, discovered a comet himself at age 20. [1]
Clyde William Tombaugh (/ ˈ t ɒ m b aʊ /; February 4, 1906 – January 17, 1997) was an American astronomer.He discovered Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt.
The 24-inch (610 mm) Dobsonian telescope brought by the Sidewalk Astronomers was unconventional, because most telescopes at such meetings tended to be smaller, on equatorial mounts, and designed for astrophotography rather than optical viewing. Surprisingly (and controversially at the time) Dobson's telescope tied in first prize for best optics.
Non-visual amateur astronomy includes the use of infrared filters on conventional telescopes, and also the use of radio telescopes. Some amateur astronomers use home-made radio telescopes, while others use radio telescopes that were originally built for astronomical research but have since been made available for use by amateurs.

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.
The Science Center houses the only optical lab for the public to grind telescope mirrors in the southeastern United States. The lab is operated by the St. Petersburg Astronomy Club. The club welcomes the public to visit the optical lab on Saturdays between 1 p.m. and 4 p.m. to build a homemade telescope from scratch.
