PERIODIC COMET 46P/WIRTANEN (12 DEC 18) Taken by Jan Curtis on December 12, 2018 @ Vail, Arizona

Moon light starting to interfere prior to comets transit at 22:30PM local time. This image: Nikon d7100, Nikkor 180 mm ED f/2.8 @ f/2.8, iso 2200, 10x50s, comet and stars fixed, PixInsight, PS 6.0 used.

For scale, I included two of Taurus brighter stars (upper right). Each are about 3.7 magnitude and are separated about ~43 (about 0.72 degree). Comet 46p coma could easily fit between them and perhaps even more in longer exposures.
