Thank-you I may have to try and visit it more often.
I was asked how this panorama was created. In answer its not mine and
I don't know, sorry. I just linked to it because it looked nice.
Whether I could get the same effect with my camera and panosaurus I
don't know.
If you add some canvas to the bottom of the image to make it 2:1
dimensions it opens in a panoramic viewer very nicely too.

"Moore and Duriscoe gathered their data with a commercially available
astronomical-grade camera that they've customized. From a stationary
position, their automated digital camera photographs every corner of
the sky by taking at least 45 overlapping exposures in about half an hour.
On a computer, Duriscoe weaves together the exposures to form a single
mosaic of the heavens. In some images, he then enhances the contrast
with false color to show bright light in white, reds, and oranges and
near darkness in cooler shades. The resulting data set can be
displayed as a panorama or in fish-eye--view format."
If you google for
Dan Duriscoe panorama automated
you get links to some interesting looking articles but you can't read
them without the right subscription. It may well just say he takes
lots of pictures and feeds them into panotools or realviz. If
anybodies library gives them access to:
"Title Measuring Night-Sky Brightness with a Wide-Field CCD Camera

Abstract We describe a system for rapidly measuring the brightness of
the night sky using a mosaic of CCD images obtained with a low-cost
automated system. The portable system produces millions of independent
photometric measurements covering the entire sky, enabling the
detailed characterization of natural sky conditions and light domes
produced by cities. The measurements are calibrated using images of
standard stars contained within the raw data, producing results
closely tracking the Johnson V astronomical standard. The National
Park Service has collected hundreds of data sets at numerous parks
since 2001 and is using these data for the protection and monitoring
of the night-sky visual resource. This system also allows
comprehensive characterization of sky conditions at astronomical
observatories. We explore photometric issues raised by the broadband
measurement of the complex and variable night-sky spectrum, and
potential indices of night-sky quality."
