IC 1805 Heart Nebula
IC 1805 Heart Nebula
Finally got a full set of RGB HSO on this target which I haven’t spent much time on. This bright emissions nebula sits within Perseus and is approximately 7500 light years away. It’s filled with energized hydrogen, but it’s always nice to capture some contrasting oxygen with bluish tones. Sitting in the core is Melotte 15 which is an open cluster of massive stars. Hydrogen, Sulfur and Oxygen were channeled into the hubble color palette while Red, Green Blue filters were used for star creation and color.
