First image: 0.40 cm telescope, f/3.2, CCD Starlight SXL8, 512x512x15 micron. The image has been treated with the algorithm of Larson-Sekanina (angle: 12 degrees) with a pixel-shift; show a tenous spherical covering surrounds the nucleus. It is also visible a large number of curved jets.

Second image: 0.40 cm telescope, f/3.2 , CCD Starlight SXL8, 512x512x15 micron. Image applied with sawtooth scaling.

False-color image taken with 2.8/180mm lens, CCD and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). Exposure time was 5 minutes. The field of view is 3.8x2.5 deg. North is at the top, East to the left.

The first image is a 10 second exposition. It was obtained with a 25 cm, F=1500 mm Newton and an ST-6 CCD camera (the frame is corrected for dark current and flat field). The image is 20 arcminutes long and 12 arcminutes wide. The second image has been unsharp masked to reveal subtle details in the coma. The third image is a standard rainbow mapping of different intensity levels within the coma. Approximate direction of the cometary motion and the direction towards the Sun help to interpret the picture.

First image is composite of 9 45 second exposures of Comet Hale Bopp. SBIG ST8 CCD image, taken at the prime focus of a 12 inch f5 maksutov telescope. Image has been flat fielded, but apart from that is unprocessed. Image dimensions 31 arcminutes (long axis) by 20 arcminutes (short axis) Second image is the original composite image has been unsharp masked and scaled in photoshop to reveal (what I hope are real!) streamers around the coma of the comet.

This ST5 CCD image approximages the visual appearance of Comet Hale-Bopp. I estimated the magnitude to be slighty below 3.0 at this point in time. A 65 mm Takahashi Flourite refractor on an EM-1 mount with exposure times of 3 x 60 seconds captured this image.
