I was very fortunate to find and capture comet C/2004 U1 during my Chirstmas holidays. It was really faint. The comet was near near its closest approach to earth.
A stack of about forty images at 60 seconds per image revealed its trail. So I was then able to align all the images on the centroid of the comet body and when stacked shows the comet as stationary against a background of trailing stars. Its so small it only resolved to a small dot. This is at: C/2004 U1 The trail is posted at: Trail of Comet C/2004 U1 I have the fint hairline trail circled. I was using an SBIG ST-2000 XCM CCD camera with a MiniBorg-60 as a f/5.4 telephoto lense. It was piggy backed on a 12" Meade 200LX-GPS scope.
