These images of Comet Hale-Bopp were taken with a STS5 CCD Camera. A Celestron C102 Refractor was used, 15 separate 10 second exposures were made. Superfix Image Processing Software was used. The image on the left shows the general coma region. The image on the right shows the inner coma and nuclear region. Magnitude approx. 3.0 42 degrees N Latitude. Taken from Queensbury NY in the Southeastern Adirondack Region.

A 20 second exposure taken through a wratten 25 red filter. SBIG ST8 CCD image, taken at the prime focus of a 12 inch f5 maksutov telescope. Image has been flat fielded. Image dimensions 31 arcminutes (long right ascension axis) by 20 arcminutes (short declination axis) The second image is the original composite image has and processed by substracting a blurred mask from the original using the software program Mira from Axiom research.

Image taken with a Cookbook 245 ccd camera, surplus 160 mm fl f2.8 lens, 7 x 3 second stacked exposures in 378 wide mode from my roof in the middle of Wichita. No drive was used, just a crude alt az mount and tracked & stacked exposures with Superfix. The out-of-focus looking thing at top is, I believe, one of those pesky infrared bright stars that are not focused well by lenses.

Image taken with the 80cm at F/D=15 telescope of Haute-Provence Observatory (France). The CCD images shown a series of concentric hoods. To enhance these hoods, I use the rotational gradient algorithm (S.M.Larson and Z. Sekanina, Astr.J. April 1984). A similar concentric structure has already been observed in Hyakutake comet. Some specialists think that shock waves are the origin of this concentric morphology.
