I don't think that will work, a continuum filter is a narrowband filter with the bandpass set to somewhere that hydrogen and sulfur emission don't occur. Because the image of the comet is taken with luminance filters, the stars will be smaller than the ones recorded in the comet image, and worse the comet might show up in the continuum image and be subtracted away!
