IC 1805 – The Heart Nebula – Classic colors
The Heart Nebula, 7500 light-years from the Earth.
The heart of this Heart is a globular cluster named Melotte 15.
The typical red color comes from ionized hydrogen clouds lit by the nearby stars.
This picture was taken from my Montréal backyard with a 2" telescope in a 2 hour session. Add to that a bit of equipment of course...
First image is processed with standard colors while the second uses the Hubble palette.
