But in the material for the image itself at the photographer's site,
it says the iamges were taken at a place near Yosemite (i.e. fairly dark)
and at Fremont Peak State Park, which seems to be the Silicon Valley
equivalent of Vekol Road, medium-dark, specially if there's fog covering
the urban areas. This is all narrow-band stuff (i.e. avoiding light-
pollution lines) on what is after all one of the highest surface-brightness
nebulae in the sky. I would commend the guy not for getting something
like this from less-than-perfect sites, but the large amount of time
both exposing and processing the data. See details here:
