This image of Comet Lovejoy was taken around 6 p.m. EST on 10 Jan 2015 with a Borg 60ED 240mm telescope and an Atik 460ex camera. I had noticed that the comet would be sharing the field of view with a portion of the gigantic emission nebula Sharpless 245, which is also known as the Eridanus Bubble. The Eridanus bubble is the western counterpart to Barnard's Loop in Orion; together they form one huge structure known as the Orion-Eridanus Superbubble.
To help capture both the comet and the nebula I added 90 minutes of H-alpha exposures to 23 total minutes of LRGB. There are also numerous small galaxies in the image; perhaps the easiest to see are four in a diamond shape just above the bottom edge of the image a little right of center, where the nebula is brightest. Clockwise, starting with the left one, these are PGC 14228, 14227, 213262 (the dimmest one), and 14234. These galaxies lie at a distance of about 200 million light years, or 50,000,000,000,000 times farther away than the comet.
