Heres tonights effort, taken from the Newcastle Astronomicals observing site at Shortland, Newcastle.
First one is with Berts 300mm f2.8 lens, wires of radio towers present, with unmodded 350D,
2nd is cropped with modded 350D with 6 inch f3.6 schmidt Newtownian, "Cometracker" gee what an ironic name, it was doing just that hehehe.
Both are several images stacked and contrast enhanced. No tracking though, exposures round the 1/100th sec mark. Iris used to align images on the comet.
Haze and cloud present.

Comet has a wide slightly curved tail as it loops round the Sun, not the long skinny one the N hemishere people got pre-perehelion.

Comet still readily visible at midday in 10 inch scope, way brighter then mercury.
