Comet C/2014 Q2 (Lovejoy) on January 13, 2015, approx. 7:30pm to 8:30pm from Caledonia ON.
I used my Canon 40D, Astronomik CLS light pollution clip-filter and my Tamron 300mm f/2.8 telephoto lens on my Super-Polaris EQ mount.
Settings: ISO 1600, f/2.8.
Post-processing included curves adjustments, colour balancing, and multiple iterations of layering, masking & blending to smooth out the head of the comet a little better.
Note the comet’s tail pointing downward as per the images’ orientation; eastward away from the sun’s direction.
The image on the left is a composite of 5 1-minute exposures and is stacked on the background stars. The image on the right is a composite of 8 1-minute exposures stacked on the head of the comet, hence the star trailing, indicating the comet’s direction. North is to the left in both images.
