Image has been flat fielded, but apart from that is unprocessed. Image dimensions 31 arcminutes (long axis) by 20 arcminutes
Second image is the original image has been unsharp masked in photoshop using 500% effect with a 15 pixel radius with a threshold of 0 to reveal (what I hope is real!) structure around the coma of the comet. .
