Those pano's are awesome, loving woodsy's chch one especially.
I've played around a bit with Canon's Photostich software, generally pretty good but you you really notice if the exposure etc haven't been locked in the photos you're stitching.
Here's a couple I've stitched using it.
Bridal Veil Falls, Raglan
QEII in Sydney Harbour (crappy exposure and joins...)
Nice work Conners and Woodsy:thumbsup: I should try a few more, problem with my camera is the tripod mount is offset to one side of the lens, well that's my excuse and I am sticking to it!
