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.

I appreciate your posting this, Roger, especially with the instructions
how to shoot it. We cannot see it from our house because there is a low
mountain range in the way (that's what you get for living on a fjord, I
guess) so if I want to see it I will have to make a special trip
somewhere.

Where do you live? It should move into view because it crosses the
sky in the course of the night, unless you are really far south.
