WIRTANEN WIDE-ANGLE Taken by Alan Dyer on December 8, 2018 @ near Gleichen, Alberta



This was Comet Wirtanen / 46P on December 8, 2018 with it traveling north through Eridanus about to enter Taurus for its encounter in a week or so with the Hyades and Pleiades star clusters. Orion is to the left, and Taurus with the Pleiades at top. The comet is the green glow at bottom right.

This is a stack of 6 x 2-minute exposures, tracked on the Star Adventurer Mini, with the Canon 35mm L lens at f/2.8 and Canon 6D MkII (stock) at ISO 1000.
Bands of red and brown airglow discolour the field, a common sight in this southerly area of the sky from home. I can rarely shoot wide-angle shots of Orion and not have it tinted with airglow. This was from home in southern Alberta at latitude 51° N.
