Thanks adamz. I used the twilight mode on the HX1. In this mode the camera takes 10 shots at 6 or 10fps and then automatically stacks the pictures together to get the above shot. It works great with image stabilization and on static subjects. Focal length was at 620mm equivalent,I think. It's a 20X zoom and I stink at mathematics.
If the nikon road map is real then this is something the supposed "DR enhanced exposure mode" will work like.(supposedly,if true:)
