Comet C/2015 V2 Johnson
in the Morning sky
December 9, 2016

 This bright 12th magnitude comet is currently very near the big face on spiral M51 in Ursa Major. It is one of the brightest comets in the sky currently, and displays a very nice white dust tail, with a touch of green near the central coma. This comet may reach naked eye in June of next year.

Three images are provided here. The first is a "standard" image with the comet stationary and the stars moved by in the 24 minutes of exposure. This exemplifies the star colors very well! (Multiple images of the RGB frame was trailed across the star images to color them)

The second image is with both stars and comet stationary and the comet image data was stacked upon the first frame in the sequence. Then the stars were stacked over that same single frame.

The third frame Ive marked some of the numerous galaxies that appear in this image. Interestingly enough, just by shooting this with the 12.5" rather than the 10" I gained over a magnitude in penetration. 19th mag and fainter galaxies are plentiful in this field. Note the nice trio of 18.7 mag galaxies to the right of the comet. The faint on on the right side of the trio is mag 19.5.
