Comet Utsunomiya

October 22, 1997 at 01:08 UT

This is Comet Utsunomiya. It is the result of combining 24 images, each with an exposure of 90 seconds. The first image was taken starting at 10:08pm local time on October 21^st. A Pictor 416xt was used on a Meade 10" F/6.3 telescope. Each image was corrected with a dark frame and with a flat field. Each image was median filtered prior to combining. The brightest pixel in the head of the comet was used to shift and combine the images. The resulting combined image was logarithmically stretched.
