First of all, thanks for all the great comments on yesterday's shot – as I write this it's my 11th most commented entry. Admittedly, loads of them were written by me, but it's still not bad ;-)

Anyway, here's the last in this short series and I really can't decide between this one and yesterday's. That said, if I had to choose one of them I guess it might be yesterday's. Oh, I don't know – you tell me.

One interesting point, that I nearly forgot about: the bright lines on the horizon (towards the left-edge of the image, and from the right edge to around a quarter of the way in) are boat trails; i.e. boats moving along the horizon during this eight minute exposure.

On a related note: I bought one of those little spirit levels that you attach to the flash hot-shoe of your camera the other day and I have to say that it was brilliant for night photography. Under normal circumstances getting the horizon level at night – i.e. when you probably can't see it – is a bit of a hit or miss affair. The spirit level, which was only a few pounds, has already saved me loads of time and effort and I definitely recommend you get one if you're going to do any night shooting.
