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 a total of 24 hours of exposure through Ha, OIII and SII narrowband filters, a three-dimensional quality image emerged revealing fine detail throughout the full extent of this beautiful nebula.
