Aurora over Sgurr Mhairi from Sligachan Old Bridge

One of the locations from my recent 5 day phototrip up to the Isle of Skye in Scotland with Geoff Moore, Pete Rowbottom and Mark Waidson was to Neist Point lighthouse (see previous image). On the way back we had to pass Sligachan Old Bridge, so we stopped on the car park of the Sligachan Inn and walked over to the Old Bridge.

 

The sky had begun to cloud over and so we were a little disappointed when it started to roll in and obscure the starry sky. The sky had a 'hazy' look to it in certain areas with the naked eye, however, the back screen of the camera showed something a little different though, as the images appeared to have a green tinge - the Aurora Borealis. The previous night it had been very active, and some great shots were flying around social media from down at Kyle. I have subsequently found out that the Aurora, unless quite intense doesn't take on the green tinge we see on photographs. This is down to the way the rods and cones in our eyes sense colour. Colour of lower intensity is seen mainly as luminosity, but with little colour information and thus the Aurora can appear grey/milky colour. Camera's do not suffer from this and thus record the colour information differently.

 

Whilst we were stood about in the cold, some guy pulled up on the car park behind us and sat there with his engine running and headlamps ablaze - just what you need when doing long exposure astrophotography!
