Motion blur isn't caused by things moving relative to you, Ice. For example, when you shut a door in your bedroom, you don't get motion blur. Its not moving FAST ENOUGH relative to you. You don't see motion blur when trees sway in the wind, nor do you get motion blur with waves on the beach. You get motion blur when the rich dickhead down the street blows by you on his custom Ducati motorcycle, ignoring the traffic laws.
The sun is massive and turns very, very slowly. It does not turn swiftly enough for your eye, assuming you could look directly at it, to see motion blur. Given the coloring of the sun here, we have a main sequence yellow-dwarf type star, a little older than Sol. Given that main sequence yellow dwarfs share physical characteristics (That's how they get categorized) we know that this star isn't turning fast enough to have motion blur.
Now, lets assume there SHOULD be full scene blurring like there was in the initial pictures in this thread. TO have motion blur the camera itself would have to be in motion. However, we don't have anything else to indicate the camera is in motion, nor a strong enough blur to indicate the direction of that motion. This could be solved by framing the image with the edgese of a canopy, or have the camera tracking an unblurred ship.
