[QUOTE="Mike150, post: 94304, member: 2287"] If you're looking for star trails, go with long exposures, but remember that the longer you leave the shutter open, the hotter the sensor will get creating noise in the final picture. Sometimes it's better to take a series of shorter exposures and Stack them in Photoshop. If you're just looking for stars, then 30 sec is a good starting point with a relatively short lens. The longer the lens, the faster the stars will transition across the lens. A good starting point is to divide 600 by the focal length and that will give you the max allowable exposure time. So, with a 300mm lens, you'd be limited to 2 second exposures before you start detecting trails. a 20mm lens would give you 30 sec. of time before the movent is detected. [/QUOTE]
