The Heart Nebula
Talon Abraxas
The Heart Nebula is an emission nebula located in the constellation of Cassiopeia, around 7,500 light years away from Earth. It has an apparent magnitude of 18.3 and an absolute magnitude of 6.5. Sometimes, it is known as the Running Dog Nebula because, when seen through a telescope, it looks a bit like a running dog.
The nebula was given its name the Heart Nebula because of its intensely red glowing gas and dark dust lanes that form a shape that resembles a heart symbol. It forms a famous complex known as the Heart and Soul with its smaller neighbour Westerhout 5, also known as the Soul Nebula, which lies just 2.5 degrees to the southeast.
The Heart Nebula is around 150 arcminutes in size and has been given the designation of Sharpless 2-190 in the Sharpless Catalogue, as well as IC 1805. The brightest part of the Heart Nebula has the designation NGC 896 in the New General Catalogue. It is classified separately because it was the first part of IC 1805 to be discovered.
The glow of the nebula comes from the radiation of a small open cluster of stars known as Melotte 15. The cluster contains very young, blue, hot supergiant stars that are about 1.5 million years old and is located near the nebula’s centre.

In the Heart of the Heart Nebula : What excites the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. Its shape perhaps fitting of the Valentine's Day, this heart glows brightly in red light emitted by its most prominent element: excited hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the heart of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of the mythological Queen of Aethiopia (Cassiopeia). via NASA

Deep Field: The Heart Nebula

Explanation: What excites the Heart Nebula? First, the large emission nebula on the left, catalogued as IC 1805, looks somewhat like a human heart. The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by silicon (yellow) and oxygen (blue). In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their atom-exciting energetic light and winds. The Heart Nebula is located about 7,500 light years away toward the constellation of Cassiopeia. At the bottom right of the Heart Nebula is the companion Fishhead Nebula. This wide and deep image clearly shows, though, that glowing gas surrounds the Heart Nebula in all directions.

In the Heart of the Heart Nebula
“You’ll be given love. You’ll be taken care of. You have to trust it. Maybe not from the sources you have poured yours. Maybe not from the directions you are staring at. Twist your head around. It’s all around you. All is full of love.”
The Heart Nebula, or IC 1805, is a beautiful emission nebula located 7,500 light-years away in the constellation Cassiopeia. Discovered by William Herschel in 1787, it's characterized by glowing ionized hydrogen and dark molecular dust. The nebula's distinctive red color and dramatic shape are due to radiation from the nearby star cluster Melotte 15, which contains stars about 50 times brighter than our sun. A
Heart for Valentina

The Heart Nebula on the right (IC 1805, Sharpless 2-190) and Soul Nebula, left, (Westerhout 5 with the star cluster IC 1848) in Hydrogen-alpha. These two make up a massive star-forming complex in Cassiopeia about 7500 lightyears away in the Perseus Arm of our Galaxy. The bright emission nebula on the far right is the Fishhead Nebula (NGC 896, IC 1795). The small circular cloud, middle top, is another emission nebula Sh2-198, much further away, around 18,000 lightyears (still, well within the galaxy). The bright cluster of stars in the core of the Heart Nebula is Melotte 15.
Imaging Notes: 51 x 5-minute exposures stacked in PI, ZWO ASI2600MM-Pro monochrome camera cooled to -10C, 3nm Antlia Pro Hydrogen-alpha filter, William Optics SpaceCat 51 apo refractor, Sky-Watcher EQ6-R Pro mount. Shot from my backyard in coastal New Hampshire, bortle 4-ish.

The nebula glows brightly in red light emitted by its most prominent element, hydrogen, but this long-exposure image was also blended with light emitted by silicon (yellow) and oxygen (blue).

This wide and deep image clearly shows, though, that glowing gas surrounds the Heart Nebula in all directions.

Another one from last week, the core of the Heart Nebula (IC 1805) in Ha+OIII with the star cluster, Melotte 15 surrounding coils and branches of interstellar dust and gas. Gear notes: I captured all the data in my backyard with an Apertura 800mm f/4 Newtonian OTA, ZWO ASI1600MM-Pro mono camera, Antlia 3nm filters, ZWO ASI290M OAG, on the Sky-Watcher EQ6R-Pro mount with the ZWO ASIAir Plus controller.
