This set of images of Comet Hyakutake (1996B2) were taken by David Nakamoto from Stony Ridge Observatory, located in the San Gabriel Mountains north of Los Angeles, using the observatory's 6 inch f/15 refractor and a cookbook 211 CCD camera operating at the telescope's prime focus. The 15 second image was taken on March 23rd 1996 at approximately 22:00 PST.

The set shows four different views of the same image. The upper left image is a negative of the original using an unsharp mask to help bring out details. The other three used a gradient filter to transform the upper left image into pseudo 3D, using the assumption that the darker the pixel in the original the higher the supposed elevation. The illumination angle was changed between the three images to help bring out details. Despite this, very little can be made out in the inner coma of the comet.
