Being too breezy to shoot that tree again I found myself a comfortable bench by the water and experimented to see what I could achieve using the moons light only over the water.
No 1 - 10s, f/8, 75mm (stars rounded)
No 2 - 20s, f/8, 28mm
No 3 - 25s, f/8, 75mm
The exercise was basically to see the affect of longer exposures and what was achievable and not one of composition. I also used the 'long exposure' noise reduction function in camera for the first time on some shots but see no gain from it at these speeds.
The area I was at was quite busy with families out late enjoying the breeze and as often happens people speak to me and one lady came and asked me "what I was measuring as I had been sat there for a long time"? I explained I was taking pictures and showed some previews on the screen. The response was that "I must have a very 'powerful' camera. Never thought of it like that before
