I was going to cheat - I admit I thought about layering in some star trails taken the other night but I know that's against the rules so I didn't.

By 'eck - I've just seen the ISO !!!

This was taken using Night Vision effect through the side window of the car (since the blasted window motor is broken and I can't wind them down - Renaults for you) as I was driving through the gardens of Tregenna Castle Hotel on the way to circuits. It was well on its way to being pitch black so it's not done a bad job really.
