IC 1805
Also called the heart nebula, it is a large emission object in Cassiopeia that neighbors the nearby soul nebula (IC 1848) and fish head nebula (IC 1795). Inside the heart is the ionizing star cluster IC 1805. Radiation from those stars is helping to shape the pillars in the middle and the entire region, forming a heart shape. The palette used is narrowband SHO with synthetic RGB stars
