The comet Machholz with a brightness of about 4th magnitude in that day has positioned in Cassiopeia, about 6 degrees northeast from the Double Clusters. But unfortunately it was covered by thin clouds this evening, I couldn't capture clear structures of tails of comet. Actually the comet is lying just near vast diffused nebulae in Cassiopeia of IC1805 and IC1848, but this image cannot show you them.
