I was just wondering if anyone knows how accurate Stellarium is in its simulations?

I was watching Io's transit across Jupiter a couple of nights ago. Through my telescope Io was at the edge of the planet about to begin its transit, while in Stellarium it showed it as being smack in the middle of Jupiter (at the half-way point of its transit).

The location, time, DST settings and everything were configured correctly in the program. Any ideas?

Also does anyone recommend alternative software? I tried Starry Night 5 a little while ago and thought the interface and graphics were downright ugly.

Thanks.
