Heart Nebula in the Hubble Palette

Back in early December I took 22 Ha subs of the Heart Nebula (IC 1805).  Then had to wait until early January to complete the imaging. On Jan 5 and 6 captured the 20x RGB and 20 Oiii and Sii.

So here is the Heart Nebula in RGBSHO.

Dec 11, Jan 5 and 6   GT102 f/5.5   ASI1600mm
30min RGB, 300min NB (Ha, Oiii, Sii)  5.8 hrs total integration

The Heart Nebula, IC 1805, Sharpless 2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. This is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.

The very brightest part of this nebula (the knot at the western edge, lower right) is separately classified as NGC 896, because it was the first part of this nebula to be discovered. (Note: The field of view for my capture was not able to include NGC 896.)

The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.   (from Wikipedia)
