I managed to image Comet Machholz one more time before the moon's presence washed out the comet.  I was at home and there were some clouds, but the area where the comet was located was clear.

Comet Machholz on 1/14/05. Canon Digital Rebel, 800 ISO, 200mm F/2.8 (320mm Effective F.L.,) 7x60 seconds.  Stacked in Registax with dark-frame subtraction for each image.  After stacking, I made adjustments to levels, color and brightness/contrast.
