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.

Great stuff you have. I'm just getting into doing some astro work, but I doubt I'll ever invest as much as you have, but I'll be having some fun. ;-)
Thanks! well let me know if you need any help with your Astro work and I'll be happy to answer any questions.
