Notes
IC 1805 is a very faint emission nebula also known as the Heart Nebula because of its obvious shape. Within the nebula, surrounding the bright center of the Heart is a meager open cluster designated Melotte 15 containing a few bright stars (brightest star at magnitude 7.87). NGC 896 and IC 1795 comprise the smaller nebula region right of the Heart’s apex.  NGC 896 is the brighter nebula to the right of the prominent vertical dark lane. IC 1795 is the fainter nebula just left of NGC 896 and right of the Heart’s apex. At the bottom of the photo, just left of center are a few stars that make up the sparse open cluster Markarian 6 (brightest star at magnitude 8.44).  Finally, the sparse open cluster NGC 1027 can be seen in the upper left corner of the image.
