1. 12 x 20 second exposures of Hale Bopp, taken through a Lumicon Swann Band filter have been combined to create this image. Image taken using an SBIG ST8 CCD camera in medium resolution mode (18 micron pixels) Image taken through a 12 inch f5 Maksutov, field of view approximagely 0.3 degrees x 0.2 degrees

2. 12 x 20 second exposures of Hale Bopp, taken through a Lumicon Swann Band filter have been combined and processed using a rotational gradient filter, with rotation 10 degrees and amplification 10. Images obtained using 12 inch Maksutov, with SBIG ST8 CCD working in medium resolution mode (18 micron Pixels) .

3. 12 x 20 second exposures of Hale Bopp, taken through a Lumicon Swann Band filter have been combined and processed by subtracting 96% of a 20 x 20 median filtered version of each image from the original imae and averaging the 12 resulting images.
