I'd be careful with exposure lengths that long, you're pretty likely to get smudging/star trails due to the earth's rotation. But it really depends on your focal length. The "Rule of 500" gives a decent guideline:

The comet is pretty bright, as long as you have a large aperture you probably won't need very long exposures.
