Image of the comet Hale Bopp taken with a Takahashi 102 mm f/6, exp. 4' (Kodak Express Gold 400 II hyper.). The comet was of magnitude 0.2 with a naked eye visible ion tail of ~10 degrees and a diffuse dust tail of ~5 degrees, despite the Moon was in the sky.

This drawing shows an upclose view of the coma and southern jet which has dominated the comet for more than a month now. The bright area just to the left of the stellar like nucleus is ever so slightly brighter than the rest of the jet. This area can be preceived as being almost nucleus-like at times. This so-called "false nucleus" can give the comet the appearance of having an elongated nucleus when viewed at the eyepiece.

First image is a 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. Second image is a false colour version of the previous image. Third image is a 420 second exposure of Hale Bopp taken through a narrow band H20+ emission filter (7000.0 nanometers, 22nm FWHM). The camera head was guided on the motion of the comet, which gives the star trails visible in the picture. Image taken at the prime focus of a 12" Maksutov telescope, using an SBIG ST8 CCD camera, working in medium resolution mode (18 micron pixels) [Image] Fourth image is a 180 second exposure of comet Hale Bopp, taken through a narrow band continuum filter centered at 684.0nm (9nm FWHM). Image has been flat fielded, contrast and gamma scaled and a false colour pallate applied.

The Image on the left is the original, on the right was processed to show any internal structure and the main sources of the(Top) dust and Ion tails (Bottom). Taken in the presence of the waning gibbous moon. These images are through an ST-6 CCD camera attached to a 3" F6 Refractor, mounted on my NSF/AAVSO Widefield Camera Platform. Taken using an Omega B, V, & R Filter set with an inline IR Blocking filter. R=30sec, V=60sec., B=90sec. exposures. Aligned on the Comets Nucleus.
