There is a very bright comet that is easy to photograph.
The comet 17/P Holmes is in the constellation Perseus and
underwent a 17-million fold increase in brightness in
mid October. It can be viewed in most cities where it
appears about half the diameter of the moon, and from a
dark country sky the fainter outer portion is larger than
the full moon. It is a nice view in binoculars, but the
tail is very faint.

Exposures up to 2 seconds at f/4 ISO 1600 are about the
maximum to prevent overexposure.

To view the comet, google comet Holmes position and you should
get several charts to use for locating the comet. It appears
in the northeastern sky in the evening.
