Observation Deck and Telescopes

Telescope

The observation deck is 624 square feet in size. It is built out of 2" thick rubber matting for vibration isolation. The primary telescope is a 14" Meade LX600. This computer guided telescope is used for all observation events as well as the lab portion of PHYS 103 (Astronomy). Several additional scopes are setup for observations as needed including Celestron 8" SCTs, a Coronado SolarMax II, and a Stellarvue SV105 Raptor (105mm refractor).

What Can You See?

Moon and Saturn

The most spectacular viewing is of the Moon and major planets such as Jupiter, Saturn, Venus and Mars. On clear nights, you can easily see the rings of Saturn and detailed striations on Jupiter. Brighter objects such as the Great Orion Nebula, the Andromeda Galaxy and several clusters are also visible visually.

Dimmer deep sky objects are typically only visible during evenings with low humidity and not much cloud cover. On select night, deep sky cameras are utilized to display images of objects otherwise not visible though visual observations.


Bringing a Group to aPublic Observation

Groups in excess of 10 visitors should contact rbaer@siu.edu in advance of your visit to insure adequate space for your group.
