Details:
Comet C/2015 V2 (Johnson) is bright at about magnitude 7.5-8 but its antitail has been faint and elusive. Imager Chris Schur captured it well with a 2 hour comet-guided exposure. I had to go 1 hour star-guided LRGB with my Vixen f/3.8 refractor, deep enough to record Abell Galaxy Cluster 2005, to ferret out the antitail! The IAU Minor Planet Center ephemeris sure is accurate (data used to make attached animation).
