[Star Wars] How does hyperdrive space travel work?

Is it going across the galaxy in a straight line? Han says how the computer needs to navigate so it avoids collision with a star, but the switch to go into hyperdrive seems to be manual not automated. In some cases the travel seems instantaneous, but in others it looks like the travel takes days. To go from one side of the galaxy to the other in that time, it must be THOUSANDS of times the speed of light.

They still need to set a course from point A to point B. The navicomputer calculates the best path for the ship to take, based on current navigational data. While hyperspace is not realspace, it is still affected by some realspace events like a supernova, and a large enough gravity well will pull them out of hyperspace (which is how an interdiction cruiser works).

Because there are different ratings for hyperdrives, some ships do inn fact move faster than others. A general average estimate of speed, based on known distances and travel times, is about 600x the speed of light.
