20D Star Trails - Battery Life in Canon EOS Mount Posted August 28, 2005 I'm wanting to toy around with star trails with the 20D. I've tried it once many years ago with a film camera and was pretty successful, want to give the 'ol 20D a whirl at it now. How long of an exposure can I expect on the 20D before the batteries crap out on me? Also, if i have the noise reduction custom function on, i'm assuming that is pointless considering the batteries will probably die, forcing my shutter closed before the noise reduction even has a chance to work...is this true? PS, I am using the verticle grip with an extra battery. Am I too expecting too much to hope for a 3 hour exposure?
