It’s always depicted as traveling with the equator “level” relative to the camera’s arbitrary axis. The hyperdrive and sublights must enforce that. We actually never see any kind of exhaust like a star destroyer, no clue how it ominously hovers around. That adds to the menace. At Yavin 4, it approaches gun-first since it is calibrating to fire. But the equator is still level with the center of the planet it’s orbiting, or perhaps the moons orbit plane.
