I thought I would share some of the pictures that I have taken over last year. In 2020 we had one of the best apparitions of a comet that we have had in a few years. This was comet Neowise. It was discovered by NASA's Near Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) space telescope on the 27th March 2020. At the time it was a faint 18th magnitude object. By the time I photographed it on the 15th July 2020 it had reached its peak apparent magnitude of between 1.5 and 2.
This picture was taken at 2.32am looking low-down towards north as the sky was beginning to brighten with the dawn. You can see the comet's long dust tail that extended over about 10 degrees at this time. This was a single 10 second exposure (ISO3200) taken on a Nikon D90 at 45mm focal length. This is a long-period comet (with an orbital period of about 6700 years) and so we won't be seeing it again any time soon.
