Donaghadee Rainbow

Thank you very much for your visits, still getting the hang of this site, not sure if I'll manage a photo everyday, especially now winter is arriving, will see. Seems a longer description is required so here goes: It was a wild day with winds gusting at 40 knots, I thought I might get a good ND shot at Donaghadee harbour with the boats bobbing but it started to rain. I looked behind me and there was a rainbow over the lighthouse, never did a filter come off my lens so quick. Couldn't get it all in with 18mm and joining 2 shots in photoshop was near to impossible so here's a single shot as good as I could get. Not the most vivid rainbow I've ever seen but beggars can't be choosers.
