Stereo pair 1:  I made 2 exposures of the comet, the first in the morning and the second in the evening of the 12 November 2007.

The comet's movement through space in the intervening time provided the parrallax.   The photographs were all made from our back garden in Forest Row.

Stereo pair 2:   The comet imaged first thing in the morning and just before midnight on the 15th November
