Heart & Soul Nebula with Double Cluster

« PreviousBack to Astrophotography GalleryNext »

A wide-field image spanning across the constellations Cassiopeia and Perseus. Two large emission nebula, the Heart Nebula (IC1805, upper left) and the Soul Nebula (IC1848, lower left) glow strongly at the wavelength of ionized hydrogen, giving the nebula a strong red coloration. Nearby (right) lie the twin open clusters NGC 869 & 884, commonly called the "Double Cluster." These magnificent clusters can be seen with the naked eye at a reasonably dark sky site.

I have reprocessed this image in modified Hubble palette for the nebula, while the star cluster is in 'normal' RGB color.
