A nice picture David. Are you using bulb to get a 2 minute exposure? I have not tried bulb, and have not gone beyond 30 second exposures.

Yes I use the bulb setting with a remote release (bought from Chesham photographic). Also a large bag clip to hold the button down for the 2 min exposures. David
