Heart Nebula with the ZWO ASI071MC Color CMOS Camera

December 13, 2018 - Reading time: ~1 minute

This one of the Heart Nebula (IC 1805) in Cassiopeia is comprised of 27 x 600 second exposures, taken over several nights, with the ZWO ASI071MC and the William Optics GT81 APO refractor, no filters, no calibration frames, stacked in DSS, processed in PSCC 2019. This is pretty impressive for a color camera when you consider the Heart is mostly made up of glowing ionized hydrogen gas and dust (perfect for narrowband imaging), and it's a relatively dim object--with the exception of NGC 896, the bright "Fish Head Nebula" at the bottom.
