About this image

Another walk over to the local playing fields was successful. Standing in the cold wind the bands of cloud and haze started to reveal some clear gaps. This cropped image is from a set of 10 x 4s exposures taken on a static tripod-mounted DSLR and stacked in Deep Sky Stacker.

In 10 x 50 binoculars the comet looked like a slightly out of focus star with only a suggestion of its tail.
