Observer: Ralph D'Andrea
Location: Grand Junction, Colorado
Date: March 30, 1997 03:30 UT

The image was shot at 9:30 PM MST from Grand Junction, CO USA, 2 minute guided exposure, 35mm camera, 100 mm f/2.8 telephoto at f/4, Fujicolor Super G Plus 800 film.

Through 7x50s at this location, the comet has been nothing short of spectacular. Several of my other Saturday night images (of less aesthetic quality) show substantial detail in the dust tail as well. Through the guiding eyepiece (1/2"fl) of my 6" f/5 newtonian, there is an incredible amount of detail, principally concentric shells, in the coma. I've been doing this for 20 years and I've never seen anything like it (missed Comet West, for some reason) I thought the comet would have been lost in horizon murk/evening twilight this close to perihelion, but it just gets better and better.
