46P/Wirtanen 2018-Dec-15 Chris Schur

This night not only cleared suddenly after being cloudy all day, but the 50% moon set behind the trees as to not blow out this image. Here are three focal lengths of the comet not only one day from closest approach to the Earth, but making a stunning grouping with the Pleiades and Haydes star clusters! The Canon XTi (Hutech Modified) was on the back of my 10 inch inside the observatory for this set of images. The comet was, despite the very bright blue moon lit sky an easy naked eye object just four degrees south of the Pleiades.
