Sunrise over Halifax roof- and tree-tops

I let the dogs out into the garden this morning, looked up and saw this beautiful sunrise. Luckily I already had my camera out ready for a long walk today, so I nipped back in for it and quickly took some photos. This one is a combination of 3 shots merged into a panorama in Photoshop.

Camera/lens settings: ISO 200, f/8, 1/250s, 18mm, hand held.
