IC 1805 - Heart Nebula in the Hubble Palette

December 28, 2018

The clouds and icy rain are here, and I've had time to process some of the data I captured over the last two nights. Here's IC 1805 and neighboring nebulae and star clusters in hydrogen-alpha, oxygen 3, sulfur 2 using the Hubble palette (SHO mapped to RGB). The Heart swings around the north celestial pole below the "W" asterism of Cassiopeia, and with trees to the north and the house blocking the view west I don't have all night to capture data. So, I went with the 11 x 300 seconds of Ha, 21 x 300 seconds of OIII, and 13 x 300 seconds of SII. Equipment: William Optics ZS61 APO refractor, ZWO ASI1600MM-Pro monochrome camera (unity gain 139/21), Astronomik filters, iOptron CEM25P mount, INDI/Ekos/KStars running in Stellarmate/Raspberry Pi 3b+.
