First image is a 120 second exposure of comet Hale Bopp taken using a 12 inch Maksutov telescope, working at f5. Image was taken through a Lumicon Swann Band filter.. The original grey scale image has been coloured to show detail. Image obtained using an SBIG ST8 camera, working in medium resolution mode (18 micron pixels). Field of view is approximately 0.3 degree (long RA axis) by 0,2 degrees (short declination axis). The second image is a false coloured version of the above 120 second exposure of comet Hale Bopp, The third image is a tri-colour image of comet Hale Bopp made of exposures through red, green and blue filters on the morning of 24th February 1997. Red exposure was 210 seconds, Blue and green exposures were each 300 seconds.

This is 0.5 second exposure with an SBIG ST-6 CCD camera on an Meade 8" telescope. I used the same false color palette as for the Feb. 13 picture to help bring out some of the details.

Both images were taken with an 8" f10 SCT / SBIG ST-7, and Lumicon f6.3 focal reducer. Both images are the same picture, and one has a brighter setting that shows more of the tail, and some jets. The second image has the brightness reduced, and shows more of the comet itself (reduced size), with local shock wave.

First image is a 4 second exposure. The comet was photographed on un-hypersensitized Fujicolor Super G 800 Plus with an Astro-Physics 130 EDT f/8 refractor working at f/6 from the front lawn of my house in Voorhees, NJ, which is a suburb of Philadelphia. This is through quite a bit of light pollution from the city and suburbs, and the gibbous moon was also in the sky. Second image is a 30 second exposure at 10:25 UT on 25 February 1997.

First image taken through a #38 dark blue filter. The scope used was a Mead lx200 12" f/10 mounted on a permanent pier. An Optec f/3.3 focal reducer was used feeding an SBIG ST7 CCD camera. The exposure time was 10 seconds. The image has been lightly colorized. The second image is a RGB Tri-Color image was taken with the LX200 12" scope and the Optec f/3.3 focal reducer. The image is color combined, using SkyPro software, from three images as: A. Through a #25A red filter for 5 seconds. B. Through a #58 green filter for 5 seconds. C. Through a #38A blue filter for 10 seconds. No other processing was done.

The Image was taken in the presence of very strong moonlight, using a Broadband LPR Filter helped to knock down the moonlight. This increased the contrast and help in recording both the Viel Nebula & the Gamma Cygni Nebula Region in this 20 minute exposure on Royal Gold 200 Film & a 100mm Lens @ F4.

This image was taken in the Eastern sky in the vacinity of the Summer Triangle (near Deneb). This RGB Tri-Color image was taken with the LX200 12" scope and the Optec f/3.3 focal reducer. An SBIG ST7 CCD camera was used with 9 micron pixel setting.The image is color combined, using SkyPro software, from three images as: A. Through a #25A red filter for 20 seconds. B. Through a #58 green filter for 60 seconds. C. Through a #38A blue filter for 40 seconds.

The exposure time was 60 seconds through a #38A blue filter into the SBIG ST7 CCD camera at 9 micron pixel setting. The image was taken through the LX200 12" f/10 scope and the Optec f/3.3 focal reducer. Both images were processed with MIRA AL software. The "A" image is a grayscale image while the "B" is colorized using the galaxy palette. The "C" image was colorized to show interesting coma details. Images "D" and "E" were processed using SkyPro software. Image "D" is colorized using a "false color" algorithm, while image "E" is colorized using an "X-Ray" algorithm. It's interesting to note the differences that these various colorizing schemes show in the coma detail!

Hale-Bopp image shot using Kodak ASA400 slide film and a 50mm lens at f/1.7, with the camera mounted on a simple "barn door" hand guider (made by Brian Close as described in the Feb. issue of Scientific American). Exposure time was one minute in a moonlit sky.
