Details:
Comet Lemmon was moving too fast for one-minute exposures, so I changed to 30s exposures. Shot three 15-min sequences until dawn. Each sequence was stacked separately. I discovered features in the tail moved too much in the sequences to stack. These changes are shown in the annotated image.
Scope: C11 with Hyper Star, 540mm f/1.9.
