Nice upload. I thought this was like and asteroid at first. I'm really excited about the well I forgot the name but some satellite that is leaving our solar system to explore, that'll bring some great things won't it!
That's a moon?? I thought they were supposed to be round... I guess this one didn't know about that rule :-). Very nice, you do need to darken the background though to match the black in the photograph, the difference is quite obvious on my monitor.
