This image was taken using the 0.6 metre Radcliffe refractor. A 10-minute CCD image was obtained through a narrow-band filter centered at 6205 Angstroms, which included emission from H2O+ ions, while another was obtained through a second narrow-band filter centered at 6250 Angstroms, which let through dust-scattered sunlight alone. By subtracting the dust image from the dust and ions image, the tail rays were revealed.

Second image is the same image with a histogram equalization done by the commercial software Hijaak Pro (pretty low-tech, but it looks like it reveals some more of the tail and perhaps the presence of a second tail).
