Images include a wide angle shot of the comet near the rising Cygnus Milky Way, a shot of the comet and its ion tail near M27, and a very short 5 second exposure through an Astro-Physic's 130EDT refractor showing the false nucleus region and a nuclear jet, and two field stars close by.

Image taken using an Olympus OM-1 with a 300 mm, f4.5 lens, and Fuji 1600 ASA color print film. The image was then digitized from the negative, using a Minolta QuickScan slide scanner (30-bit color). Note that the blue ion tail, and the whitish dust tail are prominently separated. Also, you can see the Dumbell Nebula (M27) near the end of the blue ion tail. The comet was located at RA 20h 6m, Dec 20d 31m.

20 x 80 binocular, field of view about 3.5 degrees. Magnitude (naked eye): + 1.7. Due to city light and a very thin layer of clouds there was (almost) no tail was visible with the naked eye. In the binoculars the comet had a very bright starlike nucleus, surrounded by a bright bow. The length of the tail was about 2 degrees.

False color images. 1-minute exposure of comet Hale-Bopp taken through a 300-mm lens at f/5.4 using a 1024 x 1024 CCD detector with no filter. The field of view is 2.4 x 2.4 degrees. The inner part of the coma was saturated in order to observe the tail. North is up, West is to the right.

First image is a mosaic of 2 30 second exposures taken through a blue filter. SBIG ST8 CCD image, taken at the prime focus of a 12 inch f5 maksutov telescope. Image has been flat fielded, and gamma and contrast scaled in using Mira.. Image dimensions approx 60arcminutes (long right ascension axis) by approx 20 arcminutes (short declination axis). Second image is a false coloured version of a 60 second exposure of comet hale bopp. The image was taken through a blue filter, and has been flat-fielded and gamma scaled.

Image taken on PPF ISO 400 using a Schmidt camera (150mm, f/1.5) guided with a C-14. Exposure time was 12 minutes. We can see the bright Dumbbell nebula right of the center. The ion tail is blue and straight while the dust tail is white and curled. A green bow is visible on the front of the comet.

First image is a 60 second exposure taken through a red filter. SBIG ST8 CCD image, taken at the prime focus of a 12 inch f5 maksutov telescope. Image has been flat fielded, and gamma and contrast scaled in using Mira. Image dimensions approx 60arcminutes (long right ascension axis) by approx 20 arcminutes (short declination axis). Second image is the original 60 second exposure through a red filter has been encoded 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. Image was then false coloured to bring out detail.

The image was taken with a 12 inch Meade LX200 telescope working at f/4. I used a SBIG ST-6 and a red filter from the Kron-Cousins UBVRI filter system. I used track and accumulate with both stacking and relays active and guided on a star and not the comet itself. I used 12 stacked 10 sec exposures for a total exposure of 2 minutes.
