Description

Comet C/2017 K2 (PANSTARRS) imaged on two consecutive nights. The main image collected using a Nikon D5600 colour DSLR with 0.8x focal reducer illustrates the green colour of the coma and extent of the comet's tail. The inset image collected the following night using a monochrome camera without focal reducer better illustrates the displacement of the small nucleus and the angle between the comet's coma and tail. 

The primary image used DSS's 'comet stacking' feature to combine separately stacked mages of background stars and the comet. ASTAP was used to create the inset image using the ephemeris mode to correct for the comet's motion resulting in star trails. Images were omitted for a brief cloudy spell, accounting for the gap in the trails.
