description IC 1805 / IC 1848 complex Overview
The IC 1805 and IC 1848 complex is a massive star-forming region located in the constellation Cassiopeia, within the Perseus arm of the Milky Way galaxy. The two neighboring emission nebulas are commonly referred to as the Heart Nebula (IC 1805) and the Soul Nebula (IC 1848). These nebulas are composed of glowing gas and dust ionized by the radiation from young, hot stars in their respective central clusters. They are popular astrophotography targets for amateur astronomers due to their large apparent size and structure.

IC 1805 / IC 1848 complex ranks #32 of 812 in the Nebula ranking, behind Sh2-275, ahead of Vela Supernova Remnant.
help IC 1805 / IC 1848 complex FAQ
Where is the Heart and Soul Nebula located in the night sky?
The IC 1805 and IC 1848 complex is located in the constellation Cassiopeia, recognizable by its distinctive "W" shape. It sits within the Perseus arm of the Milky Way galaxy, roughly 7,500 light-years away from Earth.
Why are IC 1805 and IC 1848 called the Heart and Soul Nebulas?
The two neighboring emission nebulas earned their common names due to their recognizable shapes when photographed in long-exposure astrophotography. IC 1805 resembles a human heart, while IC 1848 looks slightly like a human heart or a stylized soul shape.
What equipment do I need to photograph the Heart and Soul Nebula?
To capture the deep red and pink hues of the Heart and Soul Nebula, astrophotographers use a DSLR or dedicated CMOS astronomy camera equipped with a narrowband hydrogen-alpha filter. Because they are quite faint, capturing them requires an equatorial tracking mount to take long-exposure images over several hours.
Are there any famous star clusters inside the Heart and Soul Nebula complex?
Yes, the Heart Nebula (IC 1805) contains a bright, young open star cluster at its center, designated Melotte 15. The intense radiation and stellar winds from the massive, hot stars in this cluster are what illuminate the surrounding gas and carve out the intricate shapes of the nebula.
