I always liked the galaxy backdrop at the end of empire. I think it is one of my favourite scenes in the trilogy. The rebels are being hunted with such determination that they are forced to hide at the very edge of the galaxy. Nowhere inside is safe for them.
It also gives the film a real epic feel to show the whole of the sw galaxy in the distance. In the booklet that came with "The Story of the Empire Strikes Back" vinyl LP (loved this as a kid), the backdrop was changed to a red nebula. Very attractive but not as awe inspiring as the entire galaxy.
I know I am a newbie here but can I make a plea that however you change this ending, keep it as the galaxy. When I was 11 years old the thought of my heroes out there at the edge of space just made my jaw drop when I saw it for the first time.
