Nikon D700, ISO 800,14-24mm Lens
I setup my Nikon D700 DSLR with a F2.8 14-24mm on the tripod. Set the ISO to 800 and the focal length to 15mm and took a few test shots. 15-second exposures gave me a reasonably saturated star without too much sky glow. In summary, if I had kept the shutter open for 25 minutes with a Full Moon at ISO 800, there would be nothing but a white frame to look at. By using 100 fifteen-second exposures and statistically stacking them, I was able to achieve the familiar star trail image familiar to all. Let me not forget the "1" Perseid fireball...
