2007.11.17Pigeon Point LighthouseIt was the Saturday before Thanksgiving and time for the annual relighting ceremony at historic Pigeon Point Lighthouse. They light the 4 ton first order Fresnel lens precisely at 6:00, and for five minutes they don't engage the rotation mechanism, so that time exposures are possible. Unlike last year, when we enjoyed sunset skies, this year it was FOGGY. But, that just made the beams more interesting. |

Before they illuminated the Fresnel lens, the regular rotating beacon was operating. The beacon is located on the seaward railing outside the lightroom. In this time exposure, you can see it sweeping to the front, blocked to the sides, and projecting backwards through the Fresnel lens. The Fresnel lens actually produces mini beams.

At 6:00 the beacon was extinguished and the Fresnel lens was illuminated. Its four tons of precision prisms and lenses produce an awesome light show. This year was its 135th anniversary at Pigeon Point Light Station.[click to enlarge] |

The beams, the moon and the fog made for a beautiful scene.[click to enlarge] |

At 6:05 the massive clockwork mechanism was engaged, and the lens--and the beams--began to rotate.
