Thanks guy's. I do like it but it's not that great!
Before I looked at the images last night I thought I did have some foreground. I think what happened is I started the sequence of photographs with it framed to include some foreground stuff, but didn't realise what I was actually looking at was the dark cloud on the horizon which then disappeared throughout the exposures, leaving no foreground!
Oh well
A few more of the shots which I will process next have nice foreground ... one even has a UFO
