I developed the film for seven minutes with ID-11 diluted 1:1. The comet was much brighter than I expected. My shortest exposure was 15 seconds which was almost too much. The comet noticeably moved during the exposures longer than thirty seconds. The negatives with 15 second exposure were quite good; they show the tail very nicely. I am just about to walk out in my yard and rephotograph it with 400 Delta film using a series of shorter exposures. Glen Robinson
