Located within the Constellation of Cassiopeia, the Heart Nebula is one of my favorite objects in the sky to photograph. It's simply a stunning collection of gas and dust sculpted by stellar winds of new stars.
My capture above was taken with the Hubble palette which consisted of using Ha, SII and OIII filters. At the center right is the very core of the Heart Nebula, also called Melotte 15. A small collection of new stars which are partly responsible for the shape of this nebula. The length of the nebula in this photo is roughly 50 light years, and the nebula is 2700 lights years from Earth.
A total of 22.5 hours of exposure (mostly HA) over 5 nights. More stats below:
