First image is a 300 second exposure of Hale Bopp through a narrow band H20+ emission filter (7000.0 nanometers, 22nm FWHM). The image has been processed by subtracting a 10 by 10 median filtered version of itself from 120% of the original image. This brings out the inner structures beautifully. Note that these shell structures are easy to see with the eye! Second image is the original unprocessed 300 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) Third 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. A false colour version of the 300 second exposure made using a Lumicon Swann Band filter.
