The Comet Machholz in that day was positioned around the tail of the Draco with its brightness about 7.5th magnitude. The comet has gone away from us and it was bad transparency condition, I could not detect the tails clearly. The second image taken through a focal length of 1600mm shows you a dimmed tail like structure stretched toward south direction.
