Where can I find good star charts online?

I'm going to my first star party this weekend, and the star chart I have, for some reason, is very inaccurate. It even lists Albireo as a constellation! What a joke! Anyway, I don't have time to order one for this weekend, so does anyone know where I can find one online to print out and use at the star party? Thanks!Where can I find good star charts online?3 other good answers so far; here's another great free planetarium program -- Stellarium (1). You could use it to get a portion of the sky you want a map of, set the scale where you like, and print.

Pay special attention to the controls that allow you to turn on/off the atmosphere and ground; turn on/off (separately) the constellation labels, lines, and art; turn on/off (separately) the equatorial and altazimuth grids.

Also worth checking, in case you don't already know about it, is the website for Sky %26amp; Telescope (2). Over on the left there are some useful links under "Observing" -- especially, "Interactive Sky Chart" (3).

Good luck, and dark skies!Where can I find good star charts online?

Where can I find good star charts online?Surprisingly enough (especially given the less-than-scholarly name)

Uncle Al's Sky Wheels are approximately as good as a couple of semi-expensive planespheres that I've acquired over the last few years.

For more detailed star charts, you may want to pick up something like the Peterson's Field Guide - very nice indeed - very useful in the field as well.

There is a very nice monthly star chart published every month here:

If you need a more detailed star atlas, there are two nice Japanese ones online with different limiting magnitudes:

I still prefer a bound paper atlas, and the best one I've found is:
