Its been a long time since Hale-Bopp and my last comet photograph on film. Of the remaining films available today, which would be recommended for comet photography? Given that comets tend to be greenish, I wouldn't think that the lack of red-sensitivity of many of today's films would be an issue.

Is Fuji 800 still available? I had great luck with that.

Kodak Portra 400 does well into the blue end of the spectrum, Ektar with Cyan.

Kodak E100G prefers greens and blues, but does have a decent red response.

Fujicolor 100 negative film has perhaps the best green response while maintaining good reds and blues. I find that it is the best color negative for astrophotography. Get it while you can.

Kodak Gold 100, 200, and 400 do quite well offering good colors in long exposures.

For black & white there is Acros.

Oh, I forgot. Provia 400X did a nice job for me in 2007 when comet Holmes dramatically brightened.

Both 25 minutes @ f/4 standard E-6 processing

Excellent fine grain with this fast film. The green layer is perhaps the most sensitive and will require dark skies free from light pollution and natural skyglow.
