Visible this evening: Several deep sky objects including the brightest globular cluster in our night sky, M13, the Hercules cluster. A full ist of objects we'll be looking for this evening: https://www.astronomy.com/observing/20-best-deep-sky-objects-visible-in-the-spring-sky/. These objects are all fairly faint and highly dependant on good weather conditions.
Children accompanied by adults are welcome. Dress weather appropriate for this outdoor viewing. Please note that the observation deck is not handicap accessible and is only accessible via stairs. Note that while this is an outdoor activity, you may be in close proximity to people throughout the evening. Masks for this event are optional.

Observation Deck and Telescopes
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?
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.
