I just can't resist a bright comet, even during the brightest phases of the Moon- I decided to take many short exposures to try to detect any hint of an Ion tail, rather than concentrating my efforts on the bright pseudo-nucleus. Success! Note the faint, diffuse tail trailing off to the upper-left in this image. 108mm f/4 astrograph, SBIG ST-10XE CCD Camera. 21 minutes of red, green, and blue filtered exposures each.

This is a 45 minute exposure (9x5 minute exposures) extreme processed to reveal the tail of comet 17P/Holmes. It's extremely faint but is there heading off to the upper right of the coma in this image. As the Moon moves out of the way this should give astrophotographers a better opportunity to focus on the faint structures that constitute that most important piece of a comet - its tail.
