It’s raining as I write this blog late on this Friday afternoon. Will the Observatory be open tonight?
If it is open, here are some potential targets we might share with the public.
M 45, well known in ancient times. Why on M list?
2nd handle star: Pleione, variable star BU Tau
M 42, enough mass for 10,000 Sun-size stars
M 44, Beehive Cluster, Galileo studied it in 1610
M 3, very old red giants + no O or B = 5-26 Billion years old?
NGC 2392 (the night’s feature), dense, hot core
3,000 LY distant, bubble of gas. See fringe on hat?
M 81, barred spiral, firt to give up rotation by spectroscopic analysis
M 82, Seyfert type galaxy (shiney)
