First image is a 300 second exposure of Hale Bopp through a Lumicon Swan Band Filter. The image has been processed by subtracting a 40 by 40 median filtered version of itself from 120% of the original image. Second image is the original 300 second exposure of Hale Bopp through a 12 inch f5 Maksutov telescope, taken using a Lumicon Swann band filter. Image has had a dark frame subtracted, been flat fielded, and then gamma and contrast scaled. A false colour pallate has then been applied. Third image is a false colour version of the 300 second exposure made using a Lumicon Swann Band filter.

Image taken with a Takahashi FC 65 500 mm Flourite Refractor was used. Exposures were 60 sec Red, 60sec Green and 120sec Blue through True Technology Dichroic TriColor filters. Superfix Image Processing and Tricolor Software was used. There were high thin clouds during the blue exposure. I estimate Hale-Bopp is about mag 0.5 to 0.8.

North is up, east is left, and the field of view is about 2.5 degrees square. This image is a 20 s exposure with a Photometrics CCD camera (Thomson 512 chip) and Robert Reeves' 135 mm Nikon lens at f/4, using the 0.4 m telescope at Limber Observatory as a tracking platform. The pseudocolor display emphasizes the tail structure, which was hard to see clearly due to a nearby Last Quarter Moon.

Field: 3 degrees on the long side of the image. Guide: ST4 on Comet's head. Note: the small diffused object on a side of the nucleus is the reflection typical of Schmidt cameras.

Date: March 4, 1997 06:00 UT

his image was obtained with the new infrared camera (MOICAM) on the TBL (Telescope Bernard Lyot) at Pic du Midi Observatory. The TBL is a 200 cm telescope, we used the F/D = 8 focus, so with the NICMOS III (256 x 256 pixels) the field of view is of 2 arcmin on the diagonal. This image is the result of a median on 12 single frames. The exposure time of each frame is of 0.5 second. We used a K filter which is close to be a continuum or "dust" filter. North is down. The "waves" are clearly visible like on CCD images.

First image is a five minute (300 second) exposure of comet Hale-Bopp. A 12 inch Maksutov telescope, working at a focal ratio of f5 was used with an SBIG ST8 CCD camera and a Lumicon Swann Band filter. The CCD was used in medium resolution mode, with 2 by 2 binning, giving a resultant pixel size of 18 microns. The field of view is 0.3 degrees (long axis) by 0.2 degrees (short axis). The image has been processed using Mira. A 45 by 45 median filtered masked image was subtracted from 105% of the original. A false colour pallate was then added. Second image is the original 300 second exposure used to make the top image on this page. It has been flat fielded and dark subtracted. Third image is a false colour version of the 2nd image. Fourth image is a wide field view of comet Hale Bopp. This 300 second exposure was taken through a Kodak Aero Ektar lens, stopped down to f5. A lumicon Swann Band filter was also in the optical train.
