LOVEJOY Comet Dramatic Split Tails - 1600 Iso ,f/4.8 at 40 minutes exposure using NIKON D3x + Telescope.
If You Can Find Orion, You Can Find Comet Lovejoy !
Beautiful diatomic carbon (C2) gas fluorescing in sunlight produces the coma's green color, the fainter bluish tail is tinted by emission from ionized carbon monoxide (CO+).
Lovejoy is a very long-period comet. On the way into the inner solar system, at this return, its path was indicating an orbital period of roughly 11,500 years. But the gravity of our solar system’s planets is thought to have altered the comet’s orbit a bit.
