Saying “Goodbye” to Orion.  Orion keeps marching westward 3 minutes per day and will soon no longer be visible in the early to mid evening summer skies.  April 15, 2020 by Mike Conron

Jim Wehmer just finished “refurbishing” both of our two Odyessy 8 Dobs by Coulter Optical to be used by the kiddies at Family Skywatch and Open Houses.  They can try to find objects in the sky all by themselves (under supervision).  The mirrors really cleaned up nicely.

Upcoming Meetings 2020 have been canceled until further notice

I’m rather disappointed that our plans to reach out to the community in April have been canceled due to COVID-19. After initiating the efforts to make Middle Fork River Forest Preserve an International Dark-sky Park, Dave Leake led the club’s planning with the Forest Preserve District, the local chapter of the Audubon Society, and the Depart-ment of Astronomy at the University of Illinois to organize the first annual Champaign County Dark Sky Week. Events such as these will have to wait until later in the year or next year.

Here’s a short video that introduces our club. Check it out:
