Well, strictly speaking, this is not a panorama, but it is a stitch of 5 images.
If I look closely there are a few small glitches where the stitching didn't work 100%, but not bad considering this was taken without a tripod, and with no planning except trying to capture 5 frames that could be stitched later.
