Comet C/2013 R1 Lovejoy
I easily found Comet Lovejoy using the binoculars, observing it as a faint fuzz with a greenish tinge. Using the camera and the 50mm I took a series of photos that I later stacked using Nebulosity. It made a beautiful sight high in the area below Ursa Major showing a faint tail in the images.

Comet C/2012 S1 ISON
Comet ISON proved more elusive than Comet Lovejoy and though I scanned the eastern horizon using binoculars and images I failed to spot the Comet before the approaching dawn washed out the sky. I suspect that the mountains of Glencoe blocked out my low horizon.
