I didn’t see it, since weather here has been overcast the past several days. Perhaps tonight might be good.

Anything longer than a 15 second exposure time for a normal lens will produce visible trails from the rotation of the earth. For longer lenses, shorter exposures will be needed for this, and so you might have to boost your ISO.

Since I assume you are using a digital camera, then you should not worry too much about exposure, since you can immediately check your histograms and image afterwards.

If you underexpose the image a bit, you will retain the color of the stars, which are usually overexposed in many astronomical photos.

However, the comet will only be visible right after sunset, and so there will be extensive sky light. In this case, automatic exposure might give you good results.
