The first image is taken with a Pentax 1:1.4 50mm on Kodak Tri-X-Pan and 35 sec exposure time. The 2nd image is taken withe a Pentax 1:2.5 200mm on Kodak Tri-X-Pan and 15 sec exposure time. These scanned images are not as good as the original, where you can see even better that the tail is now split in a "V" shaped form. The visual magnitude of Hale-Bopp in this morning was about Epsilon Cygnus ~ 2.5 m.

First image is a composite of two exposures, one 3 minutes, and one 5 minutes at 9:58 and 10:07 UT on 16 February 1997. The comet was photographed on gas-hypersensitized Fujicolor Super G 800 Plus with a Nikon 400mm f/2.8 ED lens from Batsto, NJ. The two original film exposures were scanned and digitized and then combined in Photoshop. Second image is Comet Hale-Bopp and the Cygnus Milky Way just before the beginning of astronomical twilight on February 16, 1997. This is a five minute exposure at 10:27 UT on gas-hypersensitized Kodak PJM Ektapress Multi-speed with a 55mm f/2.8 Nikkor lens.

Images of Hale-Bopp comet taken with a Criterion 4000 SCT 4" F5 (FL:500mm). A CCD camera SBIG ST6 was used and the exposure was 60 sec. The sky condition was not very good because a thin layer of clouds covered the comet. The blue color of the comet were added to increase the look and are not the real color of Hale-Bopp.

Two images done with the 130mm Celestron Schmidt. First image is a 5 minute exposure with red filter showing dust tail (1120 UT). Second image is a 1 minute exposure with no filter, showing ion tail as well (1135 UT). Both on hypered Kodak 2415 emulsion. These images are about 3 degrees on a side; for the unfiltered exposure north is to the left (sorry about that), while for the red-light picture the field of view is rotated about 20 degrees clockwise from that orientation. These are subsections of the camera field; the negative shows the ion tail extending off the frame (about 4 degrees from the nucleus).

First image is a 60 second exposure of Comet Hale Bopp made using a 12 inch f5 Maksutov Telescope. Images were exposed through a red filter (Wrattan 25) The image has been scaled to show detail in the coma. Conditions poor with haze and occasional low cloud. Second image is a version of the first image with a false colour pallete Third image shows the jets of Comet Hale Bopp. 60 second exposure, processed by subtracting a 10 by 10 pixel median filtered image from the original.
