Details:
Technical specs: Nikon d7100, Nikon 180mm f/2.8 @ f/4, iso=2000, exposure 59x90s.
Three versions are shown: Comet with stars (both fixed), Comet without stars, and Comet fixed.
The nucleus appeared with anti-tail, and dust/ion tail of at least 3 degrees. Comet's movement was apparent in just 10 minutes. Nearly 90 minutes of comet movement is seen by the trailing stars. The trail just left of the nucleus (small dots) in the fixed comet version may have been a slow moving satellite.
This was one of three comets I captured in about 5 hours (the other two were Comet P41 and Comet Johnson).
