Spectacular Skies at a Lighthouse
The sky and sea present an ever-changing panorama of light and colour from the view point of an Australian lighthouse.
Last week I spent a wonderful four nights at the Smoky Cape Lighthouse, in Hat Head National Park, on the Mid-North Coast of New South Wales. I was after panoramas of seascapes and cloudscapes, and the skies didn’t disappoint.
At sunset, as below, the sky to the east glowed with twilight colours, with the bright clouds providing a beautiful contrast against the darkening sky. The kangaroo at far right was an added bonus as he hopped into frame just at the right time.
At sunrise, the Sun came up over the ocean to the east, providing a stunning scene to begin the day.
The Smoky Cape Lighthouse was lit up for the first time in 1891. It was staffed for decades by three keepers and their families who lived in the cottages visible in the panoramas above. They tended to the kerosene lamps, to cleaning the lenses, and to winding the weight-driven clockwork mechanism that needed resetting every two hours to keep the reflector and lens assembly turning. By day, they would draw the curtains across to keep the Sun from heating up the optics.
The huge optical assembly uses a set of nine lenses, each a massive fresnel lens, to shot focused beams out to sea. The optics produce a trio of beams, in three sets.
Each night you could see the nine beams sweeping across the sky and out to sea, producing a series of three quick flashes followed by a pause, then another three flashes, the characteristic pattern of the Smoky Bay Light. Each lighthouse has its own flashing pattern.
The lead photo, repeated above, shows the beams in the twilight, with the stars of the Southern Cross as a backdrop. Three beams are aimed toward the camera while the other two sets of beam trios are shooting away out to sea.
The image below shows the beam trio shining out over the water toward one of the dangerous rocks off shore.
The Lighthouse was converted to electricity in 1962, when staff was reduced. Then in the 1980s all lighthouses were automated and staff were no longer needed.
While we might romanticize the life of a lighthouse keeper, it was a lonely and hard life. Keepers were usually married, perhaps with children. While that may have lessened the isolation, it was still a difficult life for all.
Today, some of the cottages have been converted into rentable rooms. I stayed in the former house of the main light keeper, filled with memorabilia from the glory days of staffed lighthouses.
The image above takes in the Southern Cross over the moonlit beach in the dawn twilight.
The last image below is my final astrophoto taken on my current trip to Australia, a 360° panorama of the Milky Way and Zodiacal Light from the back garden of the Lighthouse overlooking the beach at Hat Head National Park.
It’s been a superb trip, with over half a terabyte of images shots and processed! The last few blogs have featured some of the best, but many more are on the drives for future posts.
Now, back to Canada and spring!
