Comet Wirtanen 46P (Nov 28, 2018).jpg

Comet Wirtanen (aka 46P) as it appeared in my sky on November 28, 2018 with it still only 17° above my southern horizon, so partly in haze. The comet was obvious in big 10x70mm binoculars as a large diffuse glow. Wirtanen was moving north and had just entered my western Canadian sky the week I took this.

As I write this, Wirtanen will be higher in mid-December when it is closest to the Sun and to the Earth.

This is a stack of six 2-minute exposures guided on the stars, with a single exposure blended in, to provide a “core” that is not streaked from the slight motion that did occur over the 12 minutes of shooting. This was with the A&M 106mm apo refractor at f/6 and Canon 6D Mark II at ISO 3200, with the Hotech field flattener.
