Finally got a little time to play with this and so far it looks like in order to get the best results, I would need to do HDR / AEB techniques because I can't get scenes like the Death Star explosion to have bright stars and not have an overblown explosion (no pun intended). The dynamic range of the shot isn't there without it. It's a bit frustrating at this point. If anyone has any settings they recommend for the flash and/or camera to try, I am all ears.

Update: I might have the Aperture set too small. I will play with it more this weekend. Here is an interesting article that might help. http://petapixel.com/2012/05/18/how-to-scan-film-negatives-with-a-dslr/
