This comet is still visibile in binoculars (unfortunately not in AU :mad2: ) but here in Holland it is north of Cassiopeia (the opposite part of the sky of of Musca ;-)) I made a rather good pic of this comet despite light pollution thanks to my new Hutech LPS filter.
5 frames each 60 sec with Canon EF 85mm f/1.8 squeezed to f/2.5, ASA 1600.
Used with the Hutech filter which allows to expose twice as long as without filter before it fogs yellow from the light pollution. Much better than the Astronomik as there is no blue tinge in the pictures. Post processed with Deepskystacker and further edited by Darktable (photo 1) and Photoshop (photo 2).
The red stain above the comet appeared to be a gas nebula NGC 7822 (http://en.wikipedia.org/wiki/NGC_7822) and is no image artefact as I thought.
The artefacts on the bottom are trees due to tracking as they moved relative to the stars.

The TIFF from DSS and the XMP from darktable the background blurred and subtracted with Photoshop :
