|Comet C/2014 Q2 Lovejoy on January 6, 2015.|
The recent full moon challenged viewing, but tonight, January 7, in the Northern Hemisphere the moon rises about 3 hours after sunset. Once the sky is fully dark (approximately 6:30 pm in mid northern latitudes), you'll have roughly an hour of dark sky viewing before the approaching moon brightens your sky. Tomorrow, January 8, your dark sky window extends roughly 6:30 - 8:30.
You don't need fancy equipment to see this comet. It's bright enough to see with binoculars, or in test exposures taken with a 24mm or 50mm lens or to find in a 70-200 mm zoom at the widest 70 mm focal length. For the next few nights Comet Lovejoy will be to the right of the constellation Orion. +Universe Today provides a handy finder chart in their article "Finding Lovejoy: How to Follow the Path of Comet 2014 Q2 Through January".
I captured the test image above with the nearly-full moon in the sky, using a Canon 70D DSLR and EF 70-300 mm f/4-5.6 lens on a star-tracking mount. If you don't have a star tracking mount, no problem, just use your widest lens (I'd use an EF 16-35 mm f/2.8 lens wide open at f/2.8 and at it's widest focal length of 16mm). Crank up the ISO and take a number of long test exposures to determine which combination of ISO and exposure time work well on your camera.
If the skies remain clear I should be able to capture even better images during moonless hours in the coming nights.
