  Three representations of the same data, stacking on the stars, tracking the comet and then a negative stretch to bring out the faint asteroid (99248) noted by Nick James in his observation on the same night.
Each pane is 16 x 16 arc minutes with north up.  At the time of the images the comet's head was near RA 04h 59m, +45d 54m Dec.  In the first pane some star magnitudes are shown with decimal points removed, i.e. 96 = mag 9.6 etc.
