Extractions: Ramsden Observatory is located on Earth's Moon, in the center of Sinus Medii (literally "The Bay of the Center"), at Lunar geographical coordinates degrees North, degrees East. This location is the Moon's sub-terrestrial point ). The Observatory is named for the British mathematician Jesse Ramsden , who showed that Cassegrain's design for a reflecting telescope reduces the spherical aberration introduced by curved lenses and mirrors( Ramsden Observatory is owned and operated by the Intersettlement Geographic Society, the 23rd century descendant of the National Geographic Society that was founded on January 27, 1888, in the city of Washington DC, the capital of the old, pre-CEGA United States of America. Beginning in the late 21st century, the Society used the Observatory to monitor conditions on Earth during the 100 years of chaos commonly referred to as "The Fall." Today, the Ramsden Observatory continues to study the Earth from afar, under the watchful eyes of the Central Earth Government and Administration. The Observatory welcomes visitors with open arms; there is nothing more beautiful in the entire Solar System than the Homeworld hovering directly overhead!

He took over the business of Jesse Ramsden in Piccadilly when Ramsden died in 1800. Berge made stick and marine barometers and some are signed "Berge London, late Ramsden".

He was also the first to observe a double star through a telescope.
