minute piggyback exposure is a last glimpse of Sagittarius
for this season. The constellation pointing to the center of
our galaxy, The Milky Way, and many bright nebula, globular
clusters, even a star cloud or two, none of which are visible
due to Light Pollution.

to the Light Pollution from the Front Range, which runs
down the central longitude of Colorado and can now be
seen from Wyoming to New Mexico and almost to the
The image above was centered on Sagittarius
the unfortunate coincidence of also being in line with the
Denver, Longmont, Greeley light dome, 90 - 40 miles away.
As is evident in this picture the full 25* of the sky is
obscured by light pollution (a tiny bit of of haze). At the
bottom of this image, the 'Gamma' was detended 90% to
show the radical difference LP causes.
The light streaks are from jets coming and going to
Denver International Airport as well as the streaks of
several street lights. With the center of the 'D-L-G' light
dome being closer to the left (south) side of this image.
In the last 10 years local amateur astronomers have
had to travel eastward to find dark skies to view the heavens,
at about the rate of 2 miles/year. As it stands now, we are
6 miles closer to Sterling to the east, than we are from
Ft. Collins to the west. If this situation continues, in another
10 years or so we will be observing under the Sterling light
dome which will obscure the sky to the east. Many
astronomical clubs are experiencing the same problem and
are working with the International Dark-Sky Association,
to fight Light Pollution, which also has monetary, health and
The increasing interest is not only due to the effects on t he sky, but
effects it has on migrating
and indiginous wildlife and dirunal health issues on people. Also contrary to popular belief, there
seems to be no decrease in crime when more unshielded illumination is used at night in urban areas.
Also making strides in awareness and compiling data to document the change
in the Night Sky
for the last ten years is The National Park Service, they have been Monitoring U.S. parks, within
the Natural Lightscapes project, in an effort to make the public aware of the problem, as well as
recommending light pollution abatement strategies for parks and some nearby concerned towns,
that recognise a dark night sky is a virtue in attracting tourist trade.
if you would like to see the Milky
Way again or for the first time, the recommend
to your cities that measures be enforced so that proper luminaries are used, that
these lights be shielded and pointed level with the horizon, and used only where
and when needed.
Light Pollution Horror Story about a Golden, Colorado Auto Dealership
What could be worse than living next to a car dealership that lights up
dozens of blocks of
residences at night and has the blessing of the local city government backing their flagrant
disregard for city code, even to the point of changing the law in order to protect businesses
and car dealerships rights to light pollute the area. Read about the action when 1 man did
the city's job and fought this injustice, even to the point where he had to mortgaged his own
U.S. Light Pollution Measures
Do We Need 8000 New Street Lights in Colorado Springs?
Colorado Springs & surrounding area residents:
is a major lighting proposal that will definitely affect many communities
Colorado Springs. This proposal includes an installation of 8,000 new street lights
around the Colorado Springs area. Even though the proposal is local, many cities and
towns 20-50 miles away will be affected by this measure if it comes to light.
OF DECEMBER 18TH, 2009 THE CITY COUNCIL HAS APPROVED
APPROPRIATIONS FOR THIS PROJECT.
With the e-mails of mayor, city council memebers and commisioners.

councils switching off street lights to save money
News - UK,
10 November 2010
Many councils are turning off street lights as a means of saving money, BBC Newsnight
has learned. Of 75 councils it spoke to in England and Wales, 32 said they would turn
some lights off, nine are dimming lights and 14 considering street light cutbacks.
There are is no statutory obligation for councils to light the streets and flicking the
switch is a cost-effective option in a time of austerity cuts...
