Public Events
The Second Saturday of every month the Club has a "Rain or Shine" presentation on an astronomy topic. The presentations are given in the Community Room at the Library unless otherwise noted.
Next Event: Jeff Annis will discuss how to inexpensively build a large Dobsonian telescope at home using common materials on Saturday May 12 at 8:00 pm, Pewaukee Public Library, 210 Main Street, Pewaukee. Please note the time change to 8 PM. The event is free and intended for a general audience.
We have moved the starting time to 8 PM during the summer months because the later time may enable us to show the night sky after the presentation, weather permitting.
