Wow this is fabulous Doug - I love it. I have that Arcsoft Panorama Maker but I have never used it to such effect. Yes a twilight one with enough light to show detail but with the city lights on could look awesome, but I also like the daylight like this. My father spent many years in Vancouver and the west coast of USA before and after the war I have whole box of pics and other junk from there at that time - good to see an up to date pic ;)

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
