hahaha how the hell would I track rockets with a tripod??? I'd need to know the flight path and explosion height - impossible.
taken with a Canon 30D and a 70-200L f4.0, handheld, if you want I'll look out exposure details from the original files, but I am guessing the exposure would be something like ISO 200/400, f4 and 1/250s
I usually take sports photos, and again you track and shoot.
Also you are working with short exposures, it really aint that hard to get them sharp if you sort your exposure.
