This post shows that same area of sky (here at top) also setting into the west. But that’s the only area of sky familiar to northern hemisphere stargazers.
Everything below Orion and Sirius is new celestial territory for the northern astronomer. Welcome to the fabulous southern hemisphere sky.
And to the autumn sky – From home it is spring. From here in the southern hemisphere summer is giving way to cool nights of autumn.
Straight up, at centre, is the faint Milky Way area containing the constellations of Puppis and Vela, formerly in the constellation of Argo Navis.
Below, the Milky Way brightens in Carina and Crux, the Southern Cross, where dark lanes divide the Milky Way.
At right, the two patches of light are the Large and Small Magellanic Clouds, satellite galaxies of our Milky Way.
The bright object at left is Jupiter rising over the Tasman Sea.
I shot this 360° panorama on March 31, 2017 from Cape Conran on the Gippsland Coast of Victoria, Australia, at a latitude of 37° South.
I’ve turned the panorama so Orion appears as we’re used to seeing him, head up and feet below. But here in the southern hemisphere the image below despicts what he looks like, as he dives headfirst into the west in the evening twilight.
The bright object here is the waxing crescent Moon, here in Taurus. Taurus is below Orion, while Sirius (the bright star at top) and the stars of Canis Major are above Orion.
This view above takes in more of Canis Major. Note the Pleiades to the right of the Moon.
Visiting the southern hemisphere is a wonderful experience for any stargazer. The sky is disorienting, but filled with new wonders to see and old sights turned quite literally on their heads!
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.
The Southern Cross, the iconic constellation of the southern sky, shines high in the south on austral autumn nights.
I’m in one of my favourite places, Australia, in particular at its self-proclaimed “astronomy capital,” Coonabarabran in New South Wales. Down the road from me is the Siding Spring Observatory.
But for 3 weeks I’m using my own telescope gear to observe and photograph the fabulous southern skies.
For part of my time here I’m attending the annual OzSky Star Party, a small and rather exclusive event for observers from around the world who come here to revel in celestial wonders visible only from southern latitudes.
The lead image at top is a 7-panel panorama of the star party in action, on the grounds of the Warrumbungles Mountain Motel, with a dozen or more large and premium telescopes set up for our use.
Overhead is the arch of the southern Milky Way, with the Southern Cross here at its highest about local midnight now in early April at the start of autumn. Below the Milky Way is the Large Magellanic Cloud, a companion galaxy to the Milky Way, itself a superb target for telescopes.
To the far right in the Milky Way is Sirius amid the gum trees, and the stars of Canis Major diving into the west. To the far left are the bright star clouds of Scorpius and Sagittarius rising in the east, bringing the glowing core of our Galaxy high into the austral sky. Bright Mars and Saturn shine in and around Scorpius.
This is a view of the Milky Way everyone should see – it is should be one of the top items on any amateur astronomer’s bucket list.
Here, above, I’ve stacked images from a time-lapse to create a star trail scene with the stars of the southern sky rotating about the blank South Celestial Pole. Again, the Southern Cross is at top.
This view, above, focuses on the Milky Way of the deep south, from Vela to Centaurus, passing through Carina and Crux, with the bright Carina Nebula, the Southern Cross, and the dark Coal Sack front and centre.
Here I zoom into the Southern Cross itself, in a mosaic of 3 panels to cover the smallest constellation using a high-resolution astrograph, a 300mm f/4 lens. The Coal Sack is at lower left while numerous star clusters lie embedded within and around the Cross, including the famous “Jewel Box” at left, next to Beta Cruxis, aka Becrux.
I shot the Crux mosaic from my cottage site at Tibuc Gardens, a superb dark sky site and home to a new cottage built after the devastating bush fires of 2013 which destroyed all the other cottages I had stayed at in previous years.
There’s much more to come, as I rapidly fill up my hard drive with time-lapses and deep-sky images of the southern sky. I already have several blogs worth of images processed or about to be. In the meantime, check my Flickr site for the latest images hot off the hard drive and uploaded as best my Oz internet connectivity allows.
The Milky Way of the southern hemisphere contains some astonishing deep-sky sights.
The lead image above shows the section of the Milky Way that extends farthest south, and so is visible only from tropical latitudes in the north and, of course, from the southern hemisphere. I shot these images this past week in Australia.
The wide-angle image above takes in the southern Milky Way from Vela, at right, to Centaurus, at left. In the middle is the Southern Cross (left of centre), the Carina Nebula complex and surrounding clusters, and the False Cross at right of frame. The close-ups below zoom into selected regions of this area of the Milky Way. All are spectacular sights in binoculars or any telescope.
This image frames the left side of Crux, the Southern Cross. The bright stars are Becrux (top) and Acrux (bottom). Just below Becrux is the compact and brilliant Jewel Box cluster, aka NGC 4755. Below it are the dark clouds of the Coal Sack, which in photos breaks up into discrete segments and patches.
This region is a favourite of mine for images and for visual scanning in any telescope. The large nebula is the Lambda Centauri complex, also labelled the Running Chicken Nebula. Can you see its outline? Above it is the beautiful Pearl Cluster, aka NGC 3766.
This is the standout object in the deep south – the Carina Nebula complex. I’ve shot this many times before but this is my best take on it. At upper left is the Football Cluster, NGC 3532, while at upper right is the Gem Cluster, NGC 3293.
Seeing this area in person is worth the trip to the southern hemisphere. There are now many photographers up north who have shot marvellous images of Carina but using robotic telescopes. They have never actually seen the object for themselves. They print the images upside down or sideways, a sign of their detachment from the real sky.
You have to stand under the southern stars to really appreciate the magnificence of the Milky Way. All else is just data taking.
The Milky Way arches over our observing field at the OzSky star party in Australia.
What an amazing few nights it has been. We’ve enjoyed several clear nights under the fabulous southern Milky Way. About 40 people from around the world have had access to telescopes from 14-inch to 30-inch aperture to explore the wonders of the southern sky from a dark site near Coonabarabran, New South Wales.
I’ve seen lifetime-best views of the Tarantula Nebula, the Carina Nebula, the Horsehead Nebula, the Omega Centauri cluster, and on and on! But the views of Mars have been incredible, the best I’ve seen the planet in a decade as it is now close to Earth and high in our southern sky.
The panorama above is a stitch of 6 untracked segments taken with a Canon 60Da and 8mm fish-eye lens. Each segment is a 60-second exposure at ISO 3200.
The 360° panorama takes in the Milky Way from Canis Major setting at right, over to Scorpius and Sagittarius and the centre of the Galaxy rising at left. At top centre is the wonderful Carina and Crux area. The two Magellanic Clouds are just above the trees at centre.
At upper left is Mars, and just to the left of it is a diffuse glow – the Gegenschein, sunlight reflected of comet dust in the direction opposite the Sun. Mars is near that point now. You can just see a faint band running from the Gegenschein to the Milky Way — the Zodiacal Band of comet dust.
Here, one of our observers takes in a view through a 24-inch reflector telescope under the stars of the Southern Cross, the pattern in the Milky Way behind him.
The nights have been warm and wonderful, though a little damp and dewy after midnight. However, rain is in the forecast again, a welcome relief for most local residents who want the rain. They can have it now. We’re happy!
Two icons of the southern hemisphere sky shine side by side in the Milky Way.
Last night was a hazy one at my site in Australia, with high clouds drifting through all evening. I made the best of it and shot some constellations, including the most famous in the southern sky, the Southern Cross, or Crux. It stands at left in the frame, with its distinctive four main stars, three of the blue and the top star of the cross, Gacrux, a very orange tint.
To the left of and below Crux the Milky Way is marred by a dark cloud of interstellar dust, the Coal Sack.
To the right of the frame you can see the pink “flower” of the Carina Nebula, one of the largest star forming regions in the sky. It is flanked by several star clusters, notably the very blue Southern Pleiades, or IC 2602, shining below the Carina Nebula.
The natural haze in the sky added glows around the stars, accentuating their colours.
In all, this is one of the richest and most colourful areas of the sky. It’s a highlight of any southern sky tour.
In this image I’ve tried to render the Milky Way in a view that simulates what you see with your unaided eyes.
The result is a celestial portrait in subtle shades of black and white.
This is a photo mosaic, but processed contrary to the usual methods – eliminating colour rather than enhancing it, and reducing contrast rather than boosting it. The result is a view that I think quite nicely matches what your eyes see, though certainly from a dark site. And in this case, you would need to be in the southern hemisphere to see this sweep of the Milky Way, from Aquila at left, to the Southern Cross at right, with the bright star clouds around the centre of the Galaxy in Sagittarius and Scorpius in the middle.
I’ve removed colours except for the muted colours of stars. And I’ve tried to render the stars with an intensity and dynamic range that the eye sees but that is often lost in long exposures.
The dark lanes of dust seen here really do look like this under dark skies. The nearby Coal Sack next to the Southern Cross does look a little darker than the rest of the sky. This view also captures another effect you can see in the real sky – the brighter sky below the Milky Way plane beneath Sagittarius and Aquila – there are more stars there, which make the background sky brighter than above the Milky Way plane (along the top of the photo) where the sky is permeated by dark obscuring dust.
This scene also frames the “dark Emu” – the shape drawn in the dark lanes that looks like a flightless emu in the sky. It’s an important “constellation” in Aboriginal mythology in Australia. The emu’s head is the Coal Sack at far right, her neck the long dark lane curving up through Centaurus and Lupus, and her tail the dark lanes at left in Ophiuchus, Scutum and Aquila.
