NSA Public Star Party at Afton Forest Preserve

  • Afton Preserve 13600 Crego Road DeKalb, IL, 60115 United States (map)

The Northwest Suburban Astronomers (NSA), in cooperation with the Dekalb County Forest Preserve District, will be hosting a public star party on Saturday, May 5th, at Afton Forest Preserve, located at 13600 Crego Road, south of DeKalb, Illinois. View and learn about planets, stars and star clusters, galaxies, and nebulae with the help of NSA members and their telescopes. Observing highlights will include Venus, Jupiter and its moons, Globular Cluster M3, various galaxies in Leo and the Virgo Cluster, and many other fascinating celestial objects.

Dress for evening and bring a flashlight covered with red plastic or cellophane (red light preserves everyone’s night vision) as well as insect repellent. Please arrive around 7:45 p.m. (sunset is at 7:53). You are welcome to bring your own telescope or binoculars. In the event of inclement weather the event will be canceled. There is no cost to attend and no registration is required.
