Very nice quality pan. I see myself at the other side of the arena, under the overhang where it's pretty dark, and the image is still pretty clear.
It really took 3 hours to stitch? With a quad and 8 GB ram it should be pretty smooth. What are you running for clocks on it, and on what motherboard? (Sorry for thread derail, but im curious

)
At any rate, real neat gigapan
