Carlsbad Cavern Night Sky vs. Net Light Pollution
November 18, 2009

360* x 180* Field of View

    This half scale, 360* x 180*,  13 second CCD image, was taken by the NPS Night Sky Team based in Ft. Collins, CO,
and displays the panorama from Carlsbad Cavern in SE New Mexico.  North is at the  center and South is at both ends.
Light domes are from cities over the horizon.  From azimuth 320* - 120* are Roswell, Carlsbad and Odessa. El Paso is
from azimuth 230* - 285*.    This half scale  image is a combination of Natural Light Pollution and the natural stars
seen at that time from this site.  Also visible in this image, are the Milky Way, Pleiades, Orion Nebula, Hyades, stars
to~10.5 mag., M31, M33, M41 (Beehive cluster) and Comet Holmes, can you find it?.                 Az: 303* Alt: 28*
 Light pollution data in the form of Total Sky Brightness and Net Light Pollution is currently being reduced and
published from a decade of field trips to about 70 National Parks, in an effort to help the parks find ways to lessen
the encroachment and minimize the impact of light pollution of the night sky. It is keystone of the parks doctrine to
maintain it's orginal, historical state for the benefit of all that visit and future generations, they should have a right
to see the parks in their natural state.
