Over the past couple months Comet 46P Wirtanen has been moving closer to us on it's current orbit around the Sun. Yesterday 12/16/2018 was it's closest approach to Earth, and it also happened to be close to some very beautiful deep sky objects, the Pleiades and California Nebula. This image captured at Grand Mesa Observatory highlights this beautiful scene taken in the early morning hours of 12/17/2018.
