Comet Madness?

"In 1910, when it was announced that Halley's Comet would once again pass the earth, hysteria broke out in Europe, based on the belief that the arrival of this comet always heralded castrophe. The war of 66 A.D. that brought about the fall of Jerusalem, the devastation of Rome by the Huns in 373, the Battle of Hastings in 1066 (it is Halley's Comet that can be seen in the famous Bayeux Tapestry, announcing the death of Harold), and many other tragic events did in fact coincide with the comet's appearance.
Whether or not these occurrences actually had anything to do with the comet anxiety spread throughout Europe as soon as its impending arrival was announced, and thousands of people fled to the mountains for safety. A group of French scientists published a paper claiming that the earth would be poisoned by fumes from the comet's tail.
Reports of 'comet insanity' and suicide attempts filled the newspapers, and 'anticomet pills' guaranteeing protection from the comet's noxious fumes, where bought up eagerly.
The comet, however, came and went without much incident"

Hale-Bopp was awesome and it had the added advantage of culling the low end of the gene pool.

Home Planet does a good job, and has an orrery display as well as a sky view.
you'll also want the orbital elements, which can be put into the cometnew.csv file so you know where all the latest comets are (including Ikeya-Zhang)
Build Your Own Telescope

I'm building my own telescope, an 8 inch (wide) reflector. You can build a telescope too, very inexpensively and with modest materials.
It's very interesting and enjoyable. Try it! Maybe you'll discover a comet too someday.
True, to purchase an 8 inch reflector isn't that bad anymore, but with the skill you gain from building a small telescope you would become able to build a much larger telescope affordably; to buy one, say a 20 inch, would be beyond the financial reach of most working people, but you could reasonably build one. Many people do.
The amateur telescope making mailing list will be glad to help you out. Mel Bartels has a lot of

Nucleus closeup

I took this image of the comet nucleus from the Steward Observatory1.6m Kuiper Telescope on top of Mt. Bigelow in Arizona on March 4. I took it for a friend of mine who's trying to nail down the comet's rotational period -- difficult to do when you can only observe it for about 1/2 hour each night before it sets. This is a raw image with a log stretch -- the dynamic range in brightness between the nucleus (saturated in the center), the coma (fuzzy part around bright area), and the three faint tails heading off to the left is huge (like a factor of several thousand). The area covered by the image is 5 arcminutes on a side, 1/6 the size of the full moon. The little bright lines are cosmic ray hits on the CCD, and the fat blotches (like the one above the coma) are stars.
Comets are one of the coolest things to observe in the sky because they CHANGE like every night!
