Details:
This image is the result of averaging 14 five minute images of Comet 46P/Wirtanen which is magnitude 19.8 in this image and is 153 million miles from Earth. Dont let this very faint image of 46P disappoint you though, Comet 46P/Wirtanen is predicted to reach about magnitude 3.5 when it will only be 7 million miles from Earth on December 16 this year. The great thing about that is the comet will be 50 degrees above the western horizon when the Moon sets at 8UT (1AM in Denver)and over 6 hours will move 1 degree across Earths night sky. With binoculars the comet should have a nice tail or at least be a nice fuzzy green object in your binoculars. The other great thing about this comet is that it should be brighter than magnitude 6 and visible in the night sky from mid November until mid January. Of course, 46P is a comet and could be brighter than expected or it could be fainter than expected. If it brightens as expected it would be a great binocular or small telescope project for astronomy clubs and school programs. 46P/Wirtanen is at perihelion in its 5.43 year orbit on 12 December when it will be 98 million miles from the Sun.

As usual select the larger image to get a better resolution image.

Congrats to all those taking nice images of Comet C/2017 S3, Mars, Noctilucent Clouds and all the other wonderful images of our beautiful Earth, Solar System and Universe. The images and pictures just keep getting better and better.

Cheers
