Description (wikipedia)The
Heart Nebula,
IC 1805,
Sharpless 2-190, is 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.
[1] It is an
emission nebula showing glowing ionized
hydrogen gas and darker
dust lanes.
[2]The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense
red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This
open cluster of stars, known as
Collinder 26 or
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.
Personal noteI did not center 100% on the open cluster at the heart nebula to allow some of the spectacular dust and gas clouds from the broader heart nebula to be in the frame. Raw data was gathered during multiple nights under less-optimal conditions. Need to find a way to make the stars twinkle a bit more.
