... Easy, get a star map that has a legend to what size dot equates to then start star hopping untill you cant see them anymore! Heypresto. Do the hard yards first learn a bit while your there.
Get Astronomy 2009 from Quasar publishing or where i brought it for 29.95 Australian Geographic (yes i missed the bulk order boat on ISS..
) but this has some good star maps.!
