Hello David

Magnificent site. The popup doesn't bother me. I'm in Australia though, so
it's unlikely I will get to see the park.

I tried to find a description of how you construct the panoramas - couldn't
see one in a quick search of the site.

I'm wondering what focal length lens(es) you used and how many shots had to
be stitched to produce what appear to be full spherical images.

Regards

Michael
