Comey Lovejoy, C/2014 Q2, nearest the Pleiades star cluster, Messier 45, on the night of Sunday, January 18, 2015, with its blue ion tail almost passing over the cluster. This is a stack of 6 x 2 minute exposures at f/2.5 with the 135mm lens and Canon 5D MkII at ISO 1600, on the Sky-Watcher Star Adventurer tracker. Taken from City of Rocks State Park, New Mexico, Some haze was passing thru this night but this is a stack of the cleanest frames.
