Comet C/2003 K4

8" LX200, F6.3 focal reducer, MX5-C camera. 1 x 60sec exposure. Image captured, colour converted, colour plane adjusted with MaxIm DL. Noise reduction in Neat Image. Histogram adjustment  in PSP. As you can see, the 60sec exposure was a bit much for my tracking on this occasion and the stars have become egg-shaped.
