A 1 1/2 inch lense that was displayed in an omate frame which was placed in wooden tubes that were only a few feet long. The lense was a refractor and the telescope was 36.5 inches long. http://period5-fotheringham-2011.wikispaces.com/Galileo%27s+Telescope

It was 150 feet long and hung by ropes on a pole. It was a refracting telescope. http://en.wikipedia.org/wiki/Johannes_Hevelius

This design was an improvement of Hevelius' design. One improvement is he changed where the eyepiece was on the telescope. http://amazing-space.stsci.edu/resources/explorations/groundup/lesson/scopes/huygens/index.php

Because of its size and weight this telescope was proved to be less effective than it was thought to be.

Used the daguerreotype process created by Louis-Jacques-Mande Daugerre.

Has a 6 foot diameter primary mirror and helped to discover the first nebula.

Was the largest telescope in America for 20 years. Helped to look at a new comet in the sky.

Eight expeditions went to view Venuses transit and of around 1700 this is one of them that survived.

This was the largest achromatic refractor created ever. It was built at Lake Geneva near Chicago.

Astronomer George Hale added a spectroheliograph, which photographed the sun in one wave length of light, to a reflector. The spectroheliograph was 10 feet and mirror was 2 feet.

It used a silver coated glass mirrors that gathered light and reflected them to the focal point.

It collected more light than the 60 inch reflector and in its time period was the largest telescope ever built.

In 1932 it was discovered that radio waves came from the sky so Reber added a dish onto a telescope which caused the radio waves to bounce to a reciever. This telescope helped him to find 3 radio waves, one in the milky way, one in Cassiopeia, and one in Cygnus.

This telescope used an aluminum coated glass mirror and made it possible to see other galaxies that are close to ours. Also instead of using normal glass they used a type of glass called pyrex which was made by Corning.It was a Cassegrain telescope.

The VLA stands for Very Large Array. Arrays are a lot of telescopes working together. The VLA has the same resolving power as one telescope with a 22 mile diameter.

This is a reflecting telescope that uses a berylium metal mirror and its purpose is to study infrared light which is invisible to the human eye. The Earth's atmosphore obsorbs majority of infrared radiation.
