Mt. Tam Astronomy Night - Heavenly Vision: Galileo's Telescopes and Observations - Hosted by Friends of Mt. Tam

Featuring: Alan Agrawal, Mount Diablo Astronomical Society

HostFriends of Mt. Tam

Galileo Galilei developed a new method for reliably comprehending the world around us and, accordingly, has been called the father of modern science. We will learn how Galileo’s celestial observations dramatically changed our understanding of the universe and our place in it.

Alan Agrawal is a physician who specializes in the treatment of autoimmune diseases in the field of rheumatology. He is also an avid amateur astronomer and independent historian on the development of the telescope. He designs and builds telescopes and eyepieces, enjoys deep sky observing with his 0.6 meter telescope, is interested in the testing of optics and currently in the process of building an interferometer. He is an active member of the Antique Telescope Society and the Mount Diablo Astronomical Society, and just recently joined the San Francisco Amateur Astronomers. He has given previous talks on Galileo’s telescopes, the history of sky charts, and the life and work of Joseph von Fraunhofer.
