In nautical terms, this is known as the "Sith Wayfinder", and it works like a map or a compass or a homing beacon or something, I dunno, whatever the plot needs it to do, we literally never see it again, oh, and you plug in some 1/4" patch cables into it for some reason, what IS this franchise anymore anyway?

Amazing light work though! Hard to believe that's film and not some ultra-dslr. Where do you even get film negatives developed around here?
