FREE Stargazing Opportunities at the Camp McGregor Observatory 
Camp McGregor is located on Crispell Lake at 10380 Adams Rd., Clark Lake, MI  49234
The Jackson County Mathematics and Science Center offers free public stargazing events at the Camp McGregor Obsevatory each month (April - October).  These viewings are supported by both the Amateur Astronomers of Jackson and trained personnel from our local schools as a way to share the night sky with the community. Each stargaze event is on the third weekend of the month -- beginning shortly after dark and lasting about two hours (depending on weather). Since stargazing is an outdoor activity, be sure to dress appropriately for the changing nightime conditions in Michigan (cold, mosquitoes, dew, etc).  Viewing dates for 2015 are listed below.
