Comet C2017 T2 PanSTARRS
Observing location
Loughborough, Leicestershire, UK
Canon 1100D
Tamron 70-300 mm f5.6 zoom lens
Fixed tripod
107 x 2s; ISO 6400

This was my first attempt to find and image this comet.  Camera was mounted on fixed tripod. Approximate comet location found by star hopping, then taking 137 images, plus darks.  107 images stacked in DSS and saved as a grey scale negative image.  Stacking revealed an extremely faint object where the comet was expected (predicted by Stellarium software at mag 10.5.). Time of observation period 00:06 - 00:20 UT, 21/11/2019.  The image shown is a crop from the full scale image, placed alongside the Stellarium map.  The brightest stars nearest the comet are magnitude ~8.2-8.4 showing that the comet is much fainter than this.

Taken in freezing cold conditions. Painful fingers.
