I would not recommend leaving IS ON vs. IS OFF if shooting a comet -- if that's what you're asking ;)

That's easy.  Just sit up all night drinkin' Natty Lite and never go to bed.

Natty?

Are you Baltimore??

He is merely saying what some self proclaimed comet experts were claiming earlier this fall that based on their database of comets, that we would not be able to see it. 
A play on words ISON ISOFF.
 
It is a real unknown, and it may be spectacular or a fizzle, but I'm skeptical of anyone trying to use a database of basically different situations to make a prediction.  History has definitely shown that comets are not predictable.

Based on the research looks like the comet won't be the "light in the sky" everyone was hoping it was going to be

http://astronomia.udea.edu.co/cometspage/

Understand this may look like an off-site topic but there have been discussions about the comet on this site previously so just passing along the apparent bad news.

Hope they get it wrong and I'll be spending some cold nights out in the middle of nowhere.

Attempting to bring this topic back to the forum.  If there are people here who do astrophotography would like reading what equipment is being used.


Some comets can become VERY bright and conspicuous objects with little warning, even ones that have been observed for centuries near the Earth. I looked up one night at my Mothers house while out after dark at the Milky Way and saw a large patch that seemed unfamiliar. Turned out to be an outburst from Comet Holmes in '07

http://www.aerith.net/comet/catalog/0017P/2007.html

Comets can be small, fuzzy objects that subtend only a few arc minutes of size, requiring a mount, telescope and perhaps an hour exposure to get a good look at.

Some only need a wide angle lens, a dark sky and 15 seconds @ 3200 ISO

Too cloudy this weekend here in VA to take pictures.  Hope to get some with my 300 and 600.  Will likely shoot a number of short exposures and stack them.  Always seems to produce better results than longer exposures at high ISO.

Apparently, we'll have to wait for another comet  :(

Latest news as of 30 minutes ago is that ISON is nearly gone now.  It's already faded to less than magnitude 6 and the nucleus has all but disappeared.  Yeah, we've heard that before...but I think this time it's for real.  If anything is left, Hubble will image it in a week or so.  All that's left is dust.

Maybe with a bit of luck, we will get an increase in the number of meteors starting January 12th...However even that is looking pretty bleak at this point.
