How would star's appear to you while looking out the windows of a spacecraft traveling at the speed of light?

Lets say you are living in the future. You are on a spacecraft bound for a star that is 50 Light Years away that is about to accelerate to the speed of light (Yes, I know that in reality nothing with mass can move at Light Speed). If you were in the cockpit looking forward out the window. Would the star's ahead of you appear to stretch across the horizon while moving close or at the speed of light (Like in Star Wars)? Or how would the stars appear? Now let's say that the same spacecraft that you are traveling in is about to accelerate to a speed faster than the speed of light. How would the stars on the horizon appear? The spacecraft is Not going through hyperspace or a wormhole. It is just super cruising to its destination. Please don't even mention the long duration or dangers of interstellar travel. All I would like to know is what a person's point of view would look like looking out the windows of a spacecraft going at those speeds. Thanks!!
