Thanks Nettie, I'm hoping to make a better shot at it tomorrow, weather permitting. I'll know how to set bulb on the new camera now so I wont be as pushed for time.
No Dave, its the lights from Coolum being diffused by surf spray. The surf has been 'thumping' the past few days. I haven't really seen seen the surf but I've heard it, from a couple of km away from the beach.
