Images taken with a Meade SCT 10" F10 (FL:2500mm). I use a CCD camera SBIG ST6 and a number of 13 images exposed 2 sec were taken. All the 13 images were added and processed by unsharp masking. The blue color of the comet were added to increase the look and are not the real color of Hale-Bopp. The image is very similar as we can see now when you observe Hale-Bopp with a telescope at high magnification.

North is up, east is left, and the field of view is about 7 arcmin square. The main image is the average of three 1.2 s exposures with a Photometrics CCD camera (Thomson 512 chip) at the f/12 Cassegrain focus of the 0.4 m telescope at Limber Observatory.
The inset is a polarization image of the inner coma, to the same scale as the main image, but with brightness representing linear polarization. It was constructed by combining sums and differences of images taken through four polaroids with their transmission axes oriented at 0, 45, 90, and 135 degrees.
