C/2012 C1 (McNaught) was a comet the gained a little attention in 2012 when it reached a magnitude of 16. It has a core diameter of 6.5 miles.
At the moment it is magnitude 25.7 and is around 16 AU (1518 Million Miles) from Earth. It is not a great surpise that it can't be seen in my image but it was an interesting challenge to try and image it, I have marked it's approximate location.
