Canon's Photostitch is wonderful, though there are white splotches where my shots didn't overlap properly, and I can't bear to lop off parts of my image. Perhaps time will improve my technique.
There's a picture of this red castle between Rushton Triangular Lodge and Lincoln that, for the life of me, I cannot remember the name of. Any ideas?

Update: My sister has informed me that this is Tattershall Castle
I also seem to have taken a disproportionately large numbers of photos of Fountains Abbey.
