Planet Hopping

The sky was absolutely jam packed with contrails this morning. I figured I'd grab a few shots and make a panorama with them. Then, one thing led to another, and before I knew it I'd made a planet.

I've spent hours this evening in Hugin messing around with control points, but there are still some bits that don't quite join up. I'd probably have to use a panoramic head and a spirit level to avoid those problems ... hmmm ... I'm sure I've seen instructions for building one of those.
