Thanks. I've given this a try using hugin, and it comes out like this: https://docs.google.com/leaf?id=0B-K2H3Sd_z9AZWNiNzNiOTgtNWNhZC00NzIxLTgzMDItZDBiMWY4NTk5ZGMz&hl=en
Which is interestingly different from the previous one - not sure which I like better. A few tips on using hugin to do this instead of PTGui: - basically just adapt the instructions on the page you told me about ( http://wiki.panotools.org/Unusual_remappings - section headed 'orientation plate' ) - you need to go to the 'camera and lens' tab of hugin and select your cylindrical panorama image to set the vertical shift parameter you've calculated. - choose rectilinear projection in the stitcher tab. - then open the panorama preview window and press 'center', then 'update'. - then in the stitcher tab, do 'calculate field of view', then increase both values by about 5 degrees to make sure the whole image gets included. - then press calculate optimal size - select 'remapped images' only, under 'Normal' output. - press stitch now.
