This image of Comet Catalina was taken on December 16, 2015 from Summerland during a brief break in the cloud cover. The limited number of sub images meant it had to be pushed considerably in processing, however it does show both the ion and dust tails. North is to the lower left in the picture.
Six 90 second sub images were taken after 5.10am with a Borg 101ED in f4.3 astrograph mode with a Canon modified XSi camera at ISO 1600 and the shots were processed with dark frames in ImagesPlus.
