At last, auroras have been spotted on every planet in the solar system, thanks to the James Webb Space Telescope. The JWST’s powerful near-infrared spectrometer recently revealed Neptune’s elusive aurora in all its gently glowing glory.

Ended up with more clear skies tonight, despite the forecast. Was testing out the S&Q video mode on the new camera today and it happened to be rolling when the aurora spiked in the early evening.

I love a little moonlight with aurora photography, even a full moon.

Here's a lowres version so I don't fill up the hard drive space on our mastodon instance :)

Flashback to a couple of weeks ago, our first night arriving into Senja. Had a lot of aurora activity through the night, and a beautiful location to enjoy the photography.

Today it's still 5°C outside and rainy, and most of the snow is long gone. These heat bubbles in the Arctic look like a permanent feature of winter now. That makes life much harder for chasing auroras in the night.

Just a mild aurora event on the island of Senja, near Tromsø in Arctic Norway.

Two things I wanna point out about the techy stuff.

Firstly, the scene always always looks brighter on screen in the night than it actually captures. In this case I ended up adding another 2 stops of exposure in post, which is very naughty. Pushing an underexposed file at high ISO is a great way to maximise noise!

Second, my preference is to edit as little as possible, and dial down the saturation. The defaults are too intense for me, and very misleading.

Capture One interface, showing all my tweaks. A lot of exposure lifting in this file, and reducing contrast in general. I lift the white point for these very gentle moments. When the aurora is dancing hard I need to drop my highlights to avoid blow outs. Just depends what phase of the nordlys we're shooting.

Side by side look at before and after editing. I'm going for a lighter sky, to pull in a little of that moonlit night.

Some folks prefer a darker and punchier scene. It's a night sky after all so that's not unusual :) You get more colour when you dial up the contrast. If you're curating a set of images, you might want to balance your aurora to run alongside the other landscape scenes perhaps. It's a creative decision.
