10-inch Newtonian reflector at f/4.8 with ATK-1HS CCD camera. Composite of several exposures between 0.5 and 10 seconds.
Detailed view of the coma and the area of the core of the comet, enhanced by using a rotational gradient filtered processing. The brightest streamer we see is the beginning of the ion-tail.On the other side of the core, there are a few fainter jets, visible on most comets when approaching the Sun.
