Telescopes Brodi Kozak
What is a Telescope? A telescope is an optical instrument for making distant objects appear larger and therefore nearer. One of the two principal forms (refracting telescope) consists essentially of an objective lens set into one end of a tube and an adjustable eyepiece or combination of lenses set into the other end of a tube that slides into the first and through which the enlarged object is viewed directly; the other form (reflecting telescope) has a concave mirror that gathers light from the object and focuses it into an adjustable eyepiece or combination of lenses through which the reflection of the object is enlarged and viewed.
Types of Telescopes There are two main types of telescopes: • Refracting telescope • Reflecting telescope
Refracting Telescope A refracting Telescope is a telescope in which light from an object is gathered and focused by lenses, with the resulting image magnified by the eyepiece.
Reflecting Telescope A telescope in which light from the object is gathered and focused by a concave mirror, with the resulting image magnified by the eyepiece.

About The Mount Wilson Observatory….http://www.mtwilson.edu/vis/ “Historic Mount Wilson Observatory is an astronomical research facility located in the San Gabriel Mountains of Southern California. Located on the summit of Mount Wilson above Pasadena at an altitude of 5715 feet (1742 meters), the observatory is visible from much of the Los Angeles area. Visitors can view the historic Hooker 100-inch telescope from the Visitors' Gallery inside the dome. There is also a small astronomical museum on the observatory grounds. Picnic tables are available at the Pavilion near the main parking lot where a commanding view of the Los Angeles basin is seen on clear days.”
