Public Star Party at Afton Forest Preserve near Dekalb

  • Afton Woods Forest Preserve 13600 Crego Rd Dekalb, Illinois USA (map)

The Northwest Suburban Astronomers (NSA), in cooperation with the Dekalb County Forest Preserve District, will be hosting a public star party on Saturday, September 2nd, at Afton Woods Forest Preserve, located at 13600 Crego Road, south of Dekalb, Illinois.  Come and let NSA astronomers show you the Planets Saturn and Neptune, double stars, galactic as well as globular star clusters, our own galaxy, the Milky Way, and our “neighbor”, the Andromeda Galaxy. Club members will be on hand to answer questions on astronomy and telescopes as well. 

Dress for evening and bring a flashlight covered with red plastic or cellophane ( red light helps preserve night vision ) and don’t forget insect repellent.  Please arrive by 7:15. ( sunset is at 7:21 ) so that car headlights don’t blind other participants.  You are also welcome to bring your own telescope or binoculars.  In the event of inclement weather the event will be cancelled. There is no cost to attend and no registration is required.
