RASC National Society: The Insider's Guide to the Galaxy - De-Mystifying Magnitude and Brightness (ONLINE)
We'll give you the tools to learn astronomy on your own at home, along with some observing goals to try.
All you need is your computer! A pair of binoculars will help, but are not necessary.
Sessions are always on Tuesdays at 3:30pm ET, but frequency of sessions changes.
De-Mystifying Magnitude and Brightness - Chris Vaughan
The spring sky hosts both very bright stars and very dim galaxies.
We'll talk about the system astronomers use to measure and report the brightness of celestial objects - from luminosity to absolute and apparent brightness, to surface brightness.
We'll also showcase a few bright galaxies that Charles Messier left off his list.
