I struck out trying to image Comet Panstarrs on Sunday evening, March 24, 2013. It was just too short of a time to find it in bright twilight, bright moonlight and with its low altitude. However, I tried something to redeem myself while I still had the equipment setup. I shot the Pleiades with a bunch of 15 second unguided exposures. I managed to catch them and Comet C/2012 L2 (Linear) in the shot. This is cropped down quite a bit to just the cluster and comet.
By the way, the comet is in the lower right. Its that small greenish smudge. 🙂
