NSA Hosts Public Star Party at Marengo Ridge on October 13th

  • Marengo Ridge Conservation Area 2411 N. Route 23 Marengo, Illinois United States (map)

The Northwest Suburban Astronomers will be hosting a public star party at Marengo Ridge Conservation Area just north of Marengo, Illinois, on October 13th.  Look through NSA members' telescopes at Mars, with its polar caps and dark albedo features once again visible after the recent dust storm, Saturn and its rings, globular and open star clusters, nebulae, and even the Andromeda Galaxy.  Feel free to bring your open telescope to observe with us and receive free guidance on using a telescope from veteran observers. 

Dress for evening and bring a flashlight covered with red plastic or cellophane (red light preserves your night vision). Please arrive by 5:45 p.m. (sunset is at 6:12 p.m. ) or come early and picnic or hike the trails.  In the event of inclement weather the event will be canceled. There is no cost to attend and no registration is required.
