Many of you know that I take photographs of the sky. Mainly at night when it's clear so I can image the stars and galaxy and Moon and the occasional satellite. I was looking forward to seeing Comet ISON this winter but it melted when it went around the Sun on U.S. Thanksgiving Day. It was billed as "Comet of the Century" by the astronomy media but that was sheer hyperbole in hindsight. So I content myself with photographing grey clouds and the interesting light they may create. So it's Thursday and we walk. And take photos.
