Description:
"The heart is a part of human body that is responsible of feeling LOVE! " Since Heart Nebula resembles the human heart i thought it is the right time to share this particular nebula on Valentine's Day! Where lovers of all ages and in all places celebrate the Day of the HEARTS! The Heart Nebula (also known as the Running dog nebula, IC 1805, Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It displays glowing ionized hydrogen gas and darker dust lanes. 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 the Sun, and many more dim stars that are only a fraction of the Sun's mass.The Heart Nebula is also made up of ionised oxygen and sulfur gasses, responsible for the rich blue and orange colours seen in narrowband images. The shape of the nebula is driven by stellar winds from the hot stars in its core. The nebula also spans almost 2 degrees in the sky, covering an area four times that of the diameter of the full moon. (Wikipedia) I stacked 710 lights, with 30 darks, 30 biases, and 30 flat frames in Deep Sky Stacker, I edited the resulting image in pixinsight and photoshop. I just want to dedicate this image to my ever loving husband "the wind beneath my wings", to all people who love the beauty of the dark night including those who haven't appreciate night beauty, and to all of us astrophotographers who sacrifice our sleep just to chase light from dark...I love You all...from your Valentine!
