Photographing the aurora has been a much bigger challenge than I'd originally thought. Everything from knowing (guessing) when it'll happen, finding a location, capture, and processing has turned out to be tricky.
This is the fifth time I've been to this location so far this year, each time the signs for aurora were looking good, only for the magnetic field to collapse, or solar wind to fizzle out, but the good news is that I've found the best place to set up and have level ground for my chair. For this night we were treated to these beams around 10:30 and another show after I packed up (as I had a two hour ride home again).
I wasn't able to see these beams with the naked eye (though others said they did) because I'm extremely colourblind, so it wasn't until I got home and checked through the images that I knew what I'd captured. As I couldn't be sure when the aurora would fire up I had a timelapse running from about 10pm through to 12:30, as I couldn't use the tracking mount I had to use 10" shutter speeds which makes for very noisy images.
Normally for processing astro images I would stack about 10 images for the sky and foreground separately to reduce the noise, but the aurora was changing and shifting so fast that it's completely different in each frame and stacking doesn't work.

Amazing work! I thought you could only see this in Tasmania if you were really lucky. That you could photograph it colourblind is extra cool.

Love the colors, it's like a movie poster.

I thought this was only over northern hemisphere, e.g., northern lights. Thanks for the knowledge!

It is much more commonly seen in the northern hemisphere, partly because there is more land close to the north pole than the south pole, partly because it's also more densely populated in the north than the south, but also because the magnetic orientation favours the north.

source? as far as im aware theres no difference between the northern and southern lights, just that more people live in the arctic circle than in the antarctic circle

Honestly I have no idea, I get alerts and updates from a local guy and he posts when the space weather is looking good. He's always talking about things like "need the field strength to shift our way", "this will probably be good for the northern hemisphere but we won't see it" or "the Bz is too far north" or something. I did my undergrad in astrophysics and I still don't understand aurora, when Darren says it's on, I go 🤣
