Star Trailing
May 29th, 2010
Some magnification is needed for all deep sky objects, and even with a top notch electronic tracking system, there will still be some star distortion caused by the earth’s rotation. Since you are using the longer exposure settings, and a point-and-shoot camera, it cannot be helped. It can be minimized a bit. What you do is shorten the exposure period a little, down to 50 seconds. Keep going lower until the star is seen as a pin point. It will take many practice shots to get the balance between exposure and the distortion just right. Some people have taken beautiful shots with the star trailing that has its own beauty. But your goal is to get as clear a shot as possible.
