    While we're confessing to such shameful things, I have to admit I can
    appreciate the appearance of much antique lighting, which is almost
    always horribly polluting. Some clever engineer type oughta be able to
    make some money designing non-lightpolluting fixtures that LOOK like
    decorative acorn lights, etc. Just a dim glow sideways could look good,
    and still be a decent compromise for lighting historic areas. Even NO
    glow, so it'd just look right in the daytime.

    One thing it looked like is a flow of hot lava from a volcano.

    In fact, the yellowish color of this makes me think that it *may* not be
    as bad as it seems. Perhaps the brilliantly illuminated coastline in the
    photograph may be illuminated primarily with easily filterable low
    pressure sodium lights.

    Perhaps the most popular attraction at Griffith Observatory, a public
    observatory and planetarium in the Hollywood Hills overlooking LA, is the
    city lights. People would come up to the roof to gaze down at the lights
    even if they didn't go into the telescope dome to look upwards. I ran the
    that telescope in the '70s and almost never left the dome without gazing at
    the lights for awhile. They're really incredibly beautiful on a clear
    night. And there was no expectation of dark skies for this observatory
    even when it was built in the 1930s. It was placed near the people who
    would visit.

    Not so for Mount Wilson Observatory where the city below has grown from a
    small hamlet to a megalopolis in the last 100 years. Still, despite the
    problems the light causes for things like visual observing I almost always
    stop to gaze at the lights below if I retire before twilight (there's no
    problem for the research that's being carried out there). The Towercam at
    the top of the 150-foot solar tower telescope --
    http://www.astro.ucla.edu/~obs/towercam.htm -- is sometimes pointed towards
    the city on clear nights and the view is great (if one ignores the
    astronomical implications, of course). I'll be observing tonight and the
    "marine layer" of low clouds that sometimes creeps in will be capping the
    lights so that sight won't be available but since this will be a visual
    session with the 60" telescope everyone will be more than satisfied with
    the increased contrast of the lights above!

    When my wife and I were looking for a smaller home outside of the city
    after the kids had fled we had to decide on which lights to have available
    -- city lights or stars. I ended up winning that one, primarily because
    the cost of a city view is far higher than one of the stars.
