Cheers guys.
It's a 90 second exposure, taken at about 1.00am in the Maldives this year.
I was sat on a sunbed, mini tripod precariously balanced on the slats, with the cushions over me and the camera to try and the rain off. Needed 5 arms really!
Ron, no rush. If you can just give me the exact internal dimensions of the frame, I will make sure it bleeds behind by a couple of mm all round. I will also spend a bit more time on the processing to sharpen it up a bit.
