Astronomy Patent Prints

Edwin Lohmann invented his version of the telescope on November 27, 1906.
Lohmann's telescope is caused to turn upon its polar axis in right ascension to cause it to follow a celestial object.

Frank Trippensee patented the planetarium on March 10, 1908.
His improvements were made to have a planetarium that is less complicated, more simple, and more efficient than others previously made. Frank wrote in his patent proposal "For purely illustrative purposes scientific accuracy is not required in every detail, but while scientific accuracy may not be obtained in the sizes and operation of all the parts, it is to be held in view that the apparatus is designed simply to give a general impression or illustration of the movements and other features of certain bodies".

The Shutter operating apparatus for an observatory dome was invented by Nicholas Petros on February 27, 1968.
This invention relates to observatory domes for astronomical observatories, space satellite tracking stations, and other similar astronomical purposes.

In that same year Philip Bowditch invented the radio telescope on July 9, 1968.
There are many benefits to using a radio telescope as opposed to just a telescope itself, especially for companies such as NASA. The gain of a radio telescope increases as the diameter is increased.
