Did you know that the holographic display of your target is accurate even in supercruise? Means, if the slot of a station points at you on the hologram, it will also point at you on arrival.
This is true. But one must remember your ship hologram when no input is being given points up and to the right slightly.(not straight fwd as you are flying) So as a result you need to have to slot on the station point slightly down and to the left if you want to exit sc lined up directly in front of the slot for a straight shot in.
If you fly with the station hologram perfectly at 0,0 oriention of the Vert and horiz you will come out of sc facing and seeing slot, but you will not be lined up correctly. This can be helpful when you don't want to be hanging around outside a station lining up your approach.
Also I believe your positional relationship between ship and station etc. is locked in once you reach safe drop. Meaning moving your ship around will no longer change how you will appear in front of the station when you drop out of sc. (Idk for sure, but it seems like it )
