April 27, 1997: 3 minute fixed camera exposure with 28mm f2.8 lens and Kodak Ektapress PMJ film. Shows the Halifax Centre's observatory, illuminated with a red flashlight, in the foreground.
My first Hale-Bopp Movie in MPEG format is here. It consists of 30 frames (north down, log scaled) taken over a ~20 minute period (10:07-10:28UT) on January 30, 1997 (the individual frames were taken as described in the still images below).
My second, and much better Hale-Bopp Movie in MPEG format is here (438k). It shows the motion of the comet's nucleus with two arcs around it. Here (516k) is the same movie, but at a higher contrast. Both movies consist of 71 frames taken over about one hour beginning on Sunday, March 16 at 23:19UT with an ST8 CCD camera on a 41cm f12 Cassegrain telescope. On two occastions the telescope was moved to keep the comet on the frame. The field size is about 6.5'x10'. The only star visible on the frame was used to align all of the images. This star appears very faintly on the higher contrast movie but is actually quite bright (mag 9.9) -- it would be curious to figure out how much the comet's coma is dimming this star. The same contrast was used throughout each movie, so the brightness changes are mostly all due to the varying atmosphere as the comet became lower in the sky.
