Hi Greg,
wow! - all those shots are terrifc, but as others have said, the pano is spectacular and the detail in pic 2 with the star trails is also fantastic.
Would you mind sharing your settings for the star trails pics, including how long the shtter was open for?
All the best
Edit - wow, I just read that you took the pano ( #4 ) from your decking. Jeez, weren't you scared the world was coming to an end or something, - the colouring has a sort of armageddon look to it don't you think?
