For all the images, the total scale of the image is 40.6′′, which corresponds to a linear scale of 4.9 × 10⁴ km at the comet. N is down, E to the left. The Sun is 14.1° S of W (PA of the comet: 75.9°). (top left) Final coadded image in the R filter for comet 56P/Slaughter-Burnham, obtained on the night of 5 October 2004, with overlayed contour plot. The faintest plotted isophote corresponds to 23.36 R-mag/arcsec². (top right) The same image enhanced by means of radial renormalisation method. The white + marks the optocentre.
