Comet Holmes

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.

Example image: 36 1-second exposures added:

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.

Thanks. I'd much rather go there than add one more click to that lousy spammer
Roger Clark's site. There's just no getting away from that spammer unless
everyone put it in their spam filters and never replied to or quoted it.

I'll add my thanks to Roger as well. When it was last clear a few nights
ago we went out and had a look. Quite an unusual comet, and it looked (to
me) like a just-fuzzy star. There was no twinkling. Sadly it doesn't
look like it will be clear tonight. Oh, well!

The map they give hasn't changed for a while:

Just out of curiosity, it is going to turn and give us a tail or is it
going to continue to barrel straight at us until it hits us with such
force that it wipes out life on earth, as we know it?

It's also nice to see better images of the comet in the
alt.binaries.pictures.astro group. It's nice to see what people can do with
their camera gear when they know a little something about photography.

Thanks for the heads up, Roger, but sadly some of us are in the
southern hemisphere... )O:

But I guess it's your turn after us getting the best of McNaught...

Nyeaahhh... Whadd'ya want? An easy life?

At 1:15am tomorrow (Sunday) it'll be 5 degrees above the horizon.
(Coincidentally, 5 degrees azimuth, too)

That's covered by trees and stuff where I live (NW Syd), but you might be
luckier. Where are you, Mark?

HaHa.
Everyone should be aware that this and Bently Jr. is the infamous P&S troll
who has been haunting these newsgroups. It constantly changes
its name. The headers and its style of insults give it away.
It is best to ignore it.

Everyone should know that you're WRONG again!

LOL!!!!!!!!!!!!!!!!!!!!!!!!!!

It's nice to see that I'm not the ONLY one that realizes your photography is
pure crap. Anyone visiting the astro photo newsgroup can see what a waste of
money your camera was. Wasted on someone with no talent and no skill too. Every
one of the photos posted there is FAR BETTER than yours!

LOL!!!!!!!!!!!!!!!!!!!!!!!!!!
