Notes

NGC 896 is most often photographed as part of a wider field image that includes its larger neighbor IC 1805, The Heart Nebula. Training the Astro-Physics 160 EDF refractor on this object for nearly 8 hours of exposure in the H-alpha band, delicate features emerge in the interplay of its hotly ionized HII regions and cold, dark molecular clouds.
