Colorado astroimager Richard McCoy captured Comet PANSTARRS on Sunday, March 10, at 7:47 p.m. MDT. And that despite bright twilight and threatening clouds below. He mounted his Nikon D7000 DSLR with a Nikon 300mm lens set to f/4 on a tripod, set his camera to ISO 800, and took a 1.5-second exposure.
