@GIRUGAMESH:That Shadows of the Empire is before the Return of Jedi so that was also before Luke got a hold of his abilities. The whole being one with the force thing is passive/constant and he just delved deeper into the force for more power. As you see in the second excerpt (Shadows of Mindor) Luke did not need to reach out to it. It just came to him naturally and he could perceive something moving at a respectable fraction of light-speed.
Tracking/processing of that caliber helps a lot when you have telepathy and telekinesis that is not limited by your movement speed.
Not sure how canon that is either, but I would like to see it happen. When does he do this? Was it in space or just flying in a city? Because there is a big difference.
Galen can do it on foot, in the game, but I'm not sure if Galen did it in a cut-scene. Galen did bring down a Star Destroyer (with telekinesis) and that was an impressive show of power. Anyway, if I'm not mistaken the Force Unleashed is canon. However, I'm not sure how canon its sequel the Force Unleashed II is.
Luke could also block attacks from an AT-AT Walker in Dark Empire, and it's equipped with light turbo-lasers. I've already mentioned to you how turbolasers are light-speed in the past.
Luke was able to put up a telekinetic shield fast enough to block it. Though, it's hard to say when it was fired. As for feats of telepathy Darth Sidious could mentally dominate/enslave Byss and turn it into a dark side nexus. Obviously, Darth
Vader is not that powerful but it does set a president for it considering that he could resist Sidious' influence at the end of Return of the Jedi.
As for the population of Byss, it consisted of about 19.7 billion people. Here's a link for that.
Found some more of Luke's fight with the AT-AT Walker.
Luke's also able to deflect one of the AT-AT Walker's lasers with his light-saber.
