Called stellar aberration, this effect is tens of times larger than the better-known phenomenon of stellar parallax, which gives a clue to distances.
I appreciated Tom Gale's article on ingenious experiments to determine the speed of light, although I thought that the description of Bradley's measurements of stellar aberration raised unnecessary complications.
But this simplicity doesn't compromise the program's plotting and calculating accuracy, since you can dig a little deeper and find settings for such subtle astronomical effects as nutation, stellar aberration, and light time, as well as the common corrections made for atmospheric refraction and precession.
