Star maps can be downloaded free.

Because you generally only need the brightest subset of stars in any area, you don't even need a comprehensive one.

A star map for Mars would functionally be pretty much equivalent to an earth one, I guess, given the distances involved.




The stars would be the same, of course. Out of curiosity, I launched Stellarium, moved to Mars, set myself at 90° latitude north, and watched directly overhead. Mars north pole seems to be aligned halfway between Cygnus and Perseus, so there is no "North Star" equivalent on Mars.
