The aluminum-domed Crosby Observatory atop Orlando Science Center houses Florida's largest publicly accessible refractor telescope. This one-of-a-kind custom-built telescope, along with several smaller scopes, are available at selected times for solar and night sky viewing.
Peer through the powerful, 10-inch lens of the refractor telescope to view the planets, the four moons of Jupiter, the rings of Saturn and deep sky objects such as galaxies, nebulas and double stars.
All activities and events in the Crosby Observatory
are weather permitting only.
September 5, 2015 - May 7, 2016
First Saturday of every month, 3:00 - 5:00 p.m.
Safely gaze upon the closest star to our home planet - the Sun. Our astronomers take aim at the sun to reveal the secrets hidden behind its glare. Take a peek at the Sun’s surface to see what kind of day the sun is having. Sometimes the surface is placid and serene but more often than not, it is boiling with sunspots and solar flares.
