[Star Wars] How do they aim the death star?

Whoever aims the death star, can't just point at a planet because they aren't seeing it. They're seeing it a few minutes ago.
Would the few minutes of light difference and possible time dilation actually matter in hitting a planet with a laser?
I imagine that at a certain distance the light difference wouldn't matter and at worst you'd just skim a planet's atmosphere and roast everything on it, but then again a solar system is huge.

Given the generally predictable nature of planetary movement, automating the process of calculating "orbital lead" probably wouldn't be very difficult. In terms of hitting what it aimed at, the DS1 seemed to be working at a pretty high level in Rogue One, so there wouldn't likely be a big problem there.

About the only real issue is the human factor, if you take Tales from the Death Star as canon, where the guy who blew up Alderran was too traumatized by the experience to pull the trigger on Yavin IV.
