This images shows the innermost part of the comet's head. It is reproduced from an image that was obtained with the ADONIS adaptive optics instrument at the 3.6-metre telescope on La Silla. It is a composite of three 1-minute exposures through an infrared K-filtre centered at wavelength 2.2 microns. The field measures 13 x 13 arcseconds. The pixel size is 0.05 arcseconds. North is up and east is to the left.

These images are based on a wide-field photographic plate obtained with the 1-metre Schmidt telescope at the La Silla observatory. The exposure lasted 30 minutes and was made on sensitized Kodak IIIa-F emulsion through a red RG630 filtre. This combination registers light in the 6300 - 7000 A (630 - 700 nm) spectral region and is well suited to show the sunlight reflected from the dust particles in the coma of Comet Hale-Bopp. Each of the three photos covers the same sky area of approx. 25 x 10 arcminutes; the scale is indicated on Photo 24B/95 by a 5 arcminute bar. North is up and Eas t is to the left. At the time of this exposure, the comet was located in a very rich ste llar field in the constellation of Sagittarius (R.A. = 18 hrs 27.7 min; Decl. = -31 deg 18 min ; equinox 2000.0), and less than 10 degrees from the direction of the galactic cen tre. The distances from the Earth and the Sun were 930 and 1040 million kilometres, respectively.

A Cookbook 245 CCD was used without the low noise modification. A Meade 8" f/6.3 LX200 was used for the exposure with no guiding during the exposures. The exposures were four minutes each. For each image, a dark field was subtracted and a flat correction applied. The images were then median filtered and then the pixels were made square. A log enhancement was applied to each of the images.

This false-colour image of the large jet now observed in bright comet Hale-Bopp is a computer-enhanced version of a near-IR CCD-frame. It was obtained with the multi-mode DFOSC instrument at the Danish 1.5-m telescope on La Silla. On this photo, North is up and East is to the left. The exposure lasted 5 minutes and was made through a gunn-i filter, recording the reflected sunlight from the dusty coma of the comet at a wavelength of about 9000 A (900 nm). The image shows that the jet emerges at a distance of about 3 arcsec North-West from the centre, curves towards North and then abruptly bends 90 deg towards North-East.

This photo is a false-colour reproduction of the central part of a CCD frame taken with the Dutch 0.90-metre telescope at the ESO La Silla observatory in Chile. The pixel size is 0.44 arcsec and the field measures approx. 1.2 x 1.2 arcmin. North is up and East is to the left. It is a 2-min exposure, taken through a red filtre. It clearly shows the now famous jet extending from the centre towards upper right (North-West).
