For reference, here’s a cap of the only time ANH shows us a head-on hyperspace tunnel:
Anyone know how Adywan produced his version? His looks like this, granted, he replaced the earlier tunnel shot also:
I wonder what your version would look like, snooker, if the white center was shifted downward, even if it means zooming into the tunnel somewhat to make it fit, and maybe blurring it to compensate. I don’t know; it’s hard to say without having it in front of me to screw around with.
JEDIT: I will say, in ROTJ the center of the hyperspace tunnel appears as Adywan depicted it: toward the bottom of the window. It’s hard to show in a screenshot, but you can see it as they revert to realspace since the stars center toward the bottom of the cockpit window.
