Mate, you did well enough with the camera you have
. Gotta remember, the guys with all the neat pics also have really neat gear too....I'd like a Nikon D700 or 7000, or a Canon 5D MkII and all the groovy tracking gear and $1200 software to process it with (if I had to)....but if you can't afford it, you just have to do the best with what you have
