Ok, Would a monopod be good for Night Shots and Long exposures.?

Monopods are used when a small boost of extra stability is needed, but not enough to actually hold the camera totally still. This is most often when someone is shooting with a long telephoto lens (that's why you see sports photographers using them), rather than when someone is shooting with a slow shutter speed. Although properly braced, you can safely shoot 2 or 3 stops slower with a monopod, you cannot use one successfully for night shots or true "long" exposures. Tripods aren't as much of a hle as people think. Pick one up and get used to it. They're one of the strongest tools in any photographer's arsenal, and for night photography, they're a must.
