Hi all
PM 1-333 is a small planetary nebula that lies about a half a degree northwest of the bright variable star Mu Cephei. Bright is an understatement when it comes to Mu Cephei; it is a red giant about 100,000 times more luminous than the sun. It is sometimes referred to as Hershel's Garnet Star (S&T, November 2020, p. 56), although it appears more of a golden yellow in this image: http://www.greggsastronomy.com/IMAGES/pm-133-LRGB.jpg 1.3X crop: http://www.greggsastronomy.com/IMAGES/pm-133-LRGBcrop.jpg LRGB, 6 hours total exposure from Dark Skies New Mexico -- Clear skies, Gregg Visit my astronomy & astrophotography site http://www.greggsastronomy.com/
