4 stacked 10 second exposures of comet C/2012 F6 (Lemmon), processed a bit and inverted to bring out some more detail.
A satellite streaked across a few of the exposures and passes in front of the comet's tail. The trail is broken because there are a few second between each exposure.
Trying Nebulosity, and it adds the lines in (unpaid) demo mode.
