This is a tricolor image of Comet Hale-Bopp. Three separate images through the R, G, B filters were combined. A C-102 Refractor was used along with an ST5 CCD camera. The Comet's brightness is steadily increasing. Magnitude is about 2.5-2.8. Latitude 42.7 degrees N. Comet is now entering Sagitta. Exposures were 15 x 10 seconds Red and Green and 25 x10 seconds Blue.

First image is a 10 minute (600 second) 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 31 arcminutes (long right ascension axis) by 20 arcminutes (short declination axis) The second image has been processed by subtracting a 20 by 20 median filtered version of itself from the original, to reveal structure in the outer regions of the coma. 5 minute exposures through red, green and blue filters were combined to make the third colour image.

Image taken as I was testing focus on a Nikon 500mm f 5 lens using 35mm hypered 2415, for a thirteen minute exposure; in between the clouds, blocking everything. The camera was piggy-backed on a C-14 fork mount using an ST-4 auto guider. This negative was projected on a wall using a small ccd camera to input it into the computer.

First image is a 10 minute (600 second) 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 31 arcminutes (long right ascension axis) by 20 arcminutes (short declination axis) During the exposure the camera was guided on the motion of the comet, which means that the star images are trailed. Second image is a 10 minute exposure (started at 04:56:42) through a green filter has been processed by subtracting a 5 by 5 median filtered version of itself from the original, to reveal structure in the outer regions of the coma. Third image is 5 minute exposures through red, green and blue filters were combined to make the left colour image; the right image has been unsharp masked to reveal structure.
