The Heart Nebula, located near Cassiopeia. I love this target. For one, it looks a lot like the thing it’s named after. Second, it’s got a lot of interesting structure with all the various clouds. Just off the Heart Nebula is the Fish Head Nebula.
This is, of course, a false color image done in my favorite color scheme known as the Hubble Palette which as I have posted about before, is Red – SII, Green – Ha, Blue – OIII.
