I took some comet pictures and I stumbled on two cool things about it.
1) The comet is casting a shadow on its own tail - you can see a faint dark line down the center of the tail.
2) There's like a second faint line pointing in the opposite direction of the main tail
here's the comet at 85mm
also I think there are like 10 starlinks in this one picture, that's a new one for me, having not done much astrophotography in a while
