Details:
On the night of December 14, I used a telescope to track Comet 46P/Wirtanen. In this photo with a cumulative exposure time of 100 minutes, you can see two long tails pulled from the both side of the coma. The one on the right is the normal tail opposite the direction of the sun. The one on the left should be a rare antitail. The halo in the upper left corner should be the glare in the telescope, not the real structure.

Well done! Can you tell us something about the instrument you used?

Great process stacking Steed. I think youve captured the most detail of any of the Comet 46p Wirtanen photos that Ive seen, incuding my own crude and modest images as tracked, untracked, and no stacking.
You must owe yours to the longer total 100 minutes exposure. So you may be the only one that picked up this faint secondary antitail. Congratulations!
