Yay!
You'll have to cut your exposure time down a little now Tony. Got to get rid of the trailing.
You do need to concentrate on getting your focus too, as you know.
Take short, 8 second exposures, zoom in on the LCD screen on the camera and check. Adjust focus, then zoom in again to see if it has improved. Keep doing that, until you can't get it any better. It takes time, I know, but well worth it to capture a pleasing image.
