THE SOUTHERN WAY

La Roche Percée, Bourail

Second week of our slow exit from confinement and people are starting to forget to implement the protective measures that are still very important.

Back in October I wrote a blog post about getting a new camera setup and trying astro-photography. This is one of those photos I captured. I’ve looked at this photos a few times but it was only on my last edit check that I realised I had captured, not only, the Milky Way but the Southern Cross as well. And that’s because of the research I did for a recent blog post, Celestial Confinement, where I learned to use Alpha Centauri AB and the Southern Cross to find the South Celestial Pole.

In January of last year, I spent a few days with my friend, who was minding a house here, at La Roche Percée. Located on the coast of Bourail which is about a two hour drive north of Noumea. It’s a very popular area with one of New Caledonia’s renowned landmark, Le Bonhomme. Plenty of accommodation, from camping to four star hotel, around the area. Lots to do as well.

It was turtle nesting season and I went out in hopes of seeing baby turtles. No such luck but since there was a fairly clear sky filled with stars, I decided to test my new camera setup (the Sony A7 III with the Tamron E 28-75mm ƒ/2.8 Di III RXD lens) and my hand at capturing the night sky. I admit, I could’ve taken my time to find a better foreground interest but, in my defence, I just wanted to see how well I could capture the stars with my setup.

I hadn’t planned this shot at all. It was a spur of the moment thing when I saw the Milky Way above me. So I set my tripod right where I was and took several exposures with different settings. I noticed the longest exposure I could take without creating star trails was 15 seconds with an ISO of 6400. A longer exposure would create oval shaped stars, especially in the corners, the beginning of star trails. This shot is a 10 second exposure with ISO at a whopping 12,800. Not necessary at all but I wanted to see the amount of noise I’d get with a long exposure. Very little noticeable noise in the sky though very noticeable in the foreground. For best results, a second, very long exposure would’ve been needed for a cleaner and brighter foreground.

I looked at a lot of tutorials on how to edit the Milky Way and it took me a long time and many trials before finding my own editing process and achieve something I was happy with. No fancy Photoshop edit, just some Lightroom brush work.

It was once the photo was ready for sharing that I recognised the two bright stars of Alpha Centauri AB at the bottom of the Milky Way, and the Southern Cross just above it. I was so stoked. This, of course, was thanks to research I did a few weeks ago for my blog post Celestial Confinement. I have to say, this photo means a lot more to me now.

I got a little too excited and provided the illustrated photo to the right for those who are not into astrology. I hope you find this fascinating though or, at least, interesting. Especially for you amateurs and enthusiasts out there, who are getting into this kind of photography. Taking beautiful photos is great but having knowleadge what you’re I think it gives more meaning to your photos. Let me know what you think over on Twitter at @Hervouet.

Now please everyone, whether you’re still in auto-confinement or not, make sure you’re implementing the protective measures of washing hands, social distancing, no touching, coughing and sneezing in your elbow and when possible wear a mask and gloves. Stay safe.
