The Aurora

Firstly, my sincere thanks to our expert Astronomer:
Mr Andrew R Green BSc (Hons) FRAS, FBIS for his excellent presentation on the Aurora and extensive knowledge. His website is here

How I photographed the Aurora:

I used:

A Nikon D750 which is an Fx DSLR, a Dx is fine so long as it has MUP – mirror lock up
A Manfrotto C/F tripod
A 488 ball head – I modded mine to Swiss Arca clamps
A 20mm wide angle lens – the wider the better to get enough sky and a wide aperture to let in plenty of light
A remote trigger – Nikons ML-L3 was also useful

Camera set-up:
Turn off in camera noise reduction & high ISO noise reduction
Set a low f stop on your lens to let in most light
Switch to manual focus & focus to infinity
If your lens has vibration reduction switch it off – as always when using with a tripod
I started at ISO 1600 but 3200 or more may be neccessary
Exposure start at 10 seconds and adjust but more than 25 seconds gives star trails.
Switch to MUP
In menu settings, select the remote (if available), on most Nikons it’s:
Photo shooting menu, Remote Control Mode (ML3), 2s delayed remote (the shutter will fire after 2 seconds)
It’s difficult to operate a camera in the dark so practise or use the U1 / U2 settings to pre-load most of the settings.
Check your camera mount plate is secure and tripod solidly located

Try and choose a spot with minimal light pollution
When cold don’t change your lens outside! removing your lens risks internal condensation

Courtesy: Make sure flash is off, be aware night vision takes a while and people are easily blinded.

Unfortunately the tripod was mounted on wooden decking which may have been responsible for the slight blurring of stars but here are my shots, all look better enlarged 1 or 2 clicks.
