Description

This is my first attempt at comet Johnson (and using PI's comet alignment process). Of course I picked the evening when the comet was positioned right next to the bright star Tau Herculis (mag 3.9). I tried to use the clone stamp tool to remove most of the star's halo, but the comet's tail was intersecting it as well so that made matters even more difficult.
