Thanks all for your comments, much appreciated.
Greg - yes, I think I got there around 4am. It was a chilly start but a beautiful day in the end.
RB - me too. Damn that pesky sun for rising
I love the rays in #4, they came out the most prominent, but I agree - there's something in all of them that appeals to me.
I love how star trail shots bring out the colour in the stars.
Thanks again for your comments.
