IC 1805 The Heart Nebula

Wish I could have gotten more of the Nebula in the frame.
The Heart Nebula (also known as the Running dog 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. It is an emission nebula showing 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

So cool and refreshing. More so than most threads posted these days!

I did a widefield (28mm lens) of the Heart and Soul Nebula and surrounding countryside a few years ago.

Dang blueridge you and JC have a lot in common.
I don’t know squat what I’m looking at but to think about the size and timeline of the heavens is pretty mind blowing.

Thansk, amateur astronomy is a great hobby (a little on the expensive side, but almost anything we do tends to be expensive.)

It has been cool to watch your pics get better and better. They've all been cool, but this one is the coolest!

Great widefield, you got a lot in that pic.

So what’s the rough cost of a rig good enough to be able to capture that image? I can’t imagine it’s cheap.
In B4 $350….

I have about $3,500 in my rig so far with still more stuff
to add, upgrade.

Is it that much brighter than andromeda? That surprises me because andromeda is visible and I’ve never heard of this particular nebula

Take a look at my earlier post in this thread. You can see both the Heart Nebula and Andromeda Galaxy.

That pic is what surprised me

These pics always serve as a reminder how miniscule we are in the vastness of the universe.
