Canon A630 @ 7mm (ASA 200) through a NexStar 5i with a 25mm Plossl (afocal). Each frame is 3 sec. exposure, single frame per night.
This short animation shows both the expansion of the coma and the apparent brightening of the core of Comet Holmes (17P). Exactly the same processing was done to each frame (Aligned and contrast range expanded 45% in MaxIM)
