Here is the effect. This is a .jpg sequence of an "exit" from lightspeed. But just play it in reverse to get a "jump". Maybe add some zoom/blur effect as you want to make it better, I don't know. I don't remember if the original effect was done by myself or someone else. All I know is that added some little blur and a blue tint. (Then, on my edit, I added a rotoscoped falcon cockpit scene above it. and it worked nice enough)

I don't remember if the rules on this forum allow me to post a link to mega, but moderators would remove it if it's not the case. (then PM me if you want it)
