This is a narrowband image of the heart nebula taken from my backyard near Phoenix Arizona. I Used an 80mm Apo refractor and a CCD camera on an Orion Atlas mount which compensates for the earth's rotation allowing for long exposures of deep space objects. This is 12 hours of data captured over about 2 clear nights. the gasses that make up the nebula in this image are Hydrogen, Oxygen, and sulfur.
