If you don't mind my butting in on a question addressed to me -- I use a guide 'scope. It will guide on anything I designate. So I can choose the comet's nucleus and it will track on that. The question is, do you want it to? If you track on the comet and it's going prety fast, you'll get obvious streaking, or a series of dots, from the background stars. If you guide on a star instead, the comet may be a little more blurry, but comets are pretty fuzzy anyhow. Some people will track on the comet and then edit out star trails by use of a cloning accessory in PhotoShop. I prefer never to clone, but it's a choice. The problem is worse the faster the comet is going compared to the background. -- Joe On Friday, November 15, 2013 12:09 PM, Erik Hansen <erikhansen@thebluezone.net> wrote: Bortle comments: "Just what this event signals for the future of C/ISON, with it now exactly two weeks from perihelion, is difficult to say. Over the next few days it should become apparent whether this event is the result of a single massive release of new volatiles; the nucleus having fractured; or perhaps even a dramatic permanent, sustainable, uptick in the comet's overall brightness."> The thing to remember about comets is that you don't have to wait for the
comet of the century. Some of us won't live long enough for that anyway.
With modern equipment and internet communications you can look at them, or recent picture of them any day. There is usually one or two within the reach of hand held binoculars and at least 5 within reach of modest aperture telescopes. The eccentric orbit make them come from nowhere, and brighten dramatically. The tail geometry is highly variable and rapidly changing.
There is much more drama here than with asteroids or planets or even sun surface phenomenon. There are discussion groups available and they are even specialize into photos, observation, and discussions.
Most important for some of the followers is if you find one you get to put your own name on it. Like Levy, Macholdts, Lovejoy, McNaught, Hyakutake, Hale, Bopp.
Keep looking up DT

Bruno and I saw it Sunday morning. It wasn't the comet of the century to be sure. It was just a small smudge with no visible tail in the 14¼". I have not seen it since the outburst and tomorrow does not look good.

Has anyone here actually seen ISON recently?
If I'm reading the charts correctly it looks like tomorrow morning in northern Utah ISON will be about 21 degrees up in the SE at the beginning of nautical twilight (0612) and about 26 degrees at the beginning of civil twilight (0645).
Of course weather in northern Utah is forecast to be cloudy in the morning.
NWS is calling for clearing Monday morning. By then ISON will be 16 degrees at nautical and 20 degrees by civil.
Here's an ISON story NASA released today: http://science.nasa.gov/science-news/science-at-nasa/2013/14nov_whatsnext/
