Comment : As usual we got bad weather and I got only 14 images this night. Still that was enough to let me see some traces of the comet. Looks that I got the comet near the edge of the field of the camera. My Goto precision was not good at that time. A bit strange look of the comet, it doesn't have any bright core. The magnitude of the comet these days are about 12.
