Description

First chance to image C/2015 V2 (Johnson). The rate of movement against the background sky is minimal as its motion on this date was very nearly directly towards Earth. This makes comet and star isolation by the normal means very problematic. On this occasion the 2 hour stack is only composed of star aligned images meaning that the comet is very slightly elongated.
