Binocular comet Jacques - 31.8.2014 at 01.00 - 31.8.2014 at 01.30 Lumijoki Observation number 29788

Visibility II / V

Veijo Kallio, Oulun Arktos

The comet Jacques stands out in the image taken at a longer total exposure time with a faintly narrow tail pointing downwards to the left. Shooting a subject almost in zenith at the time of shooting proved challenging due to the bending susceptibility of the focusing device.
