Comet C/2014 Q2 (Lovejoy) imaged at WM Keck Observatory Headquarters, Waimea, on Feb 16 2015.
Calibrated with bias, dark and flatfield in IRIS, stacked in IRIS. Further processed in Fitswork and Photoshop.
I could still see the comet with my naked eye. Visual estimate: m1 = 5.2, DC = s6. Dew condensed on my lens as dew point was reached and the imaging had to be given up.
M76 is visible around the LR corner.
