The full image is available at http://gigapan.com/gigapans/116482 - there is another 180° off to the right, round to The Old Bailey
This is made up of about 20 photos taken from the roof of St Paul's Cathedral, at the bottom of the dome. I took this while spending a week in London during the Olympic games. There might be some Wenlocks and Mandevilles visible.
Given that the photos are not taken from a single point, there is a lot of overlap and distortion, and the dreaded wavey horizon. It also took quite a while to work out how to use Hugin as their doc seems to miss some vital information about what half of the options and buttons actually mean (what actually is a panosphere, and what's a stack number for), and that searching for control points in pairs of images is the best way of stiching.
Perhaps one day, I'll go back up and take one from the walkway at the very top of the dome.
