The Iris Nebula, Widefield. Taken from Bone Cave, TN, 4.1 hrs exposure time. The Iris Nebula is in the center of the frame. It's blueish tint comes from starlight being reflected off of extremely tiny particles of solid matter, up to 10 or even 100 times smaller than dust particles on Earth. It's 6 light years across, and 1,400 light years away. The dark nebula surrounding the Iris is made of dust particles coated with frozen carbon monoxide and nitrogen, which mostly block light.
