The image above shows Comet PanSTARRS (C/2011 L4) passing next to M31, the Andromeda galaxy - "next" from our vantage point, of course. In reality, they're more than a couple of million of light-years away.
The image is actually a composite of data from two different sessions. One session, the one that captured the entire field, including both the comet and the galaxy, is a two pane mosaic of only RGB data. This is the FOV presented in the image (well, the original is a bit bigger). In addition to that, I also used data from a previous session, at a time M31 is much easier to photograph (not so low in the horizon), which added a bit of punch to the entire field and much more manageable data for bringing out the details inM31.
