Comet C/2015 G2 (Masters) is a new sixth magnitude object, discovered only a month ago. I captured this image on 16th May 2015 using my Canon EOS 60D camera mounted on a Vixen Polarie, equatorial camera drive, witha 200mm lens attached.
The object will be visible throughout May but is not predicted to brighten (although it will move into a darker region of the sky).

The next image was taken two days earlier in an exploratory attempt to locate it with a 50mm lens fitted, without the motor driven mount. It is approximately centre left:
