Comet Wirtanen 46P - Dec 10, 2018 (135mm 6DII).jpg
Comet Wirtanen (aka 46P) at centre here, and to the east of the Type M red giant star Menkar in Cetus. This was the evening of December 10, 2018. The comet was easily visible to the naked eye as a fuzzy spot, though you had to know where to look.
As as side note, the star Menkar is also known as Alpha Ceti, and in the Star Trek movie The Wrath of Khan, Khan was imprisoned on planet V circling Ceti Alpha.
This is a stack of 9 x 1-minute exposures with the Canon 135mm L series lens at f/2.2, and Canon 6D MkII at ISO 1250, all aligned on the stars, plus a stack of 3 exposures taken consecutively aligned for the core and blended in with a luminosity mask to minimize trailing on the core. The camera was on the Star Adventurer Mini tracker, taken from home in southern Alberta.
