Here is the result I was able to get from a light-polluted London suburb the first night it attained enough altitude, Dec. 28/29. A single 30s exposure shows it with M79 to upper right.
A stack of 17 exposures, with extensive processing, revealed the tail (this surprised me considering the conditions and the 14 degree altitude).
Inverting this image and making it mono shows the tail better.
I could not see the comet visually with 10×50 binoculars, but I expect I soon will be able to. As it gains altitude certainly UK imagers will be able to reveal far more detail than this.
