A Large Telescope for the Nation 

The "Great Refractor" of the US Naval Observatory was the largest
telescope in the world from 1873 to 1880. It's status as the "worlds
largest" is given in comparison with other telescopes as is the
value in the context of the national contribution required to
acquire it. Also presented are aspects of this acquisition and the
various upgrades that have taken place to keep it productive into
the 21st Century including the important contributions in Solar
System and Double Star astronomy. Finally examined in detail are two
recent examples of the contributions made in the study of two
important binary stars.

 

Refreshments will be served at 3:30pm
