It's from a stack of 5 shots. F2.8, ISO 3200, 10 seconds. Nikon D850 and Nikkor 70-200 lens @ 200mm. Camera mounted on a tracker.
Tried again last night, and the comet has changed appreciably. This is a Photoshop merge of two shots from 24 hours apart. The relative positions are not correct, but exposure is the same. Lots of difference in the trail.
