Details:
An abrupt tail disconnect with comet Lemmon Friday night as the solar wind hit it with some chop. I almost didn't catch it in time to get the biggest ripple in frame. That tail is streaming away fast — frame by frame you can watch all of it breezing away from the comet's head 3-4 times faster than the comet is orbiting at a right angle off to the left.
Normally I'd integrate the images in two separate batches — one aligned to the stars, the other aligned to the coma and then re-combined for the final image. But as fast as the tail was rushing away over the course of a half hour, it smeared out a lot of that detail. So this time around I did a third alignment on the tail motion itself and melded that into the mix to sharpen it up.
