Membership meeting at Butterworth Center, 7 p.m.

Dean Regas’ presentation will be Messier objects, and how to find them. He will be joined on the video by two special guests: Vannessa Gressieux, from Noir Lab at Kitt Peak National Observatory in Tucson, Arizona, and Nick Wightman, an amateur astrophotographer and member of the Central Florida Astronomical Society. Because this is not a live presentation, there will be no Q&A session.
