This quarter-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 the 8000 ft parking lot at the top of the Capulin Volcano 45 miles SE of Raton, New Mexico.
This is a Bortle 2 class site, with a limiting magnitude of ~7.1. At low angle on this image a slight haze of airglow is discernible,
which was just barely visible to the eye.
North is at the center and South is at both
ends. Light domes are attributed to cities enumerated below the image.
0* - 90* are visible trees on the rim of the volcano itself. Also visible in this image (full scale is 13662 x 3360 pixels), are the
Milky Way, Pleiades, Orion Nebula, Hyades, stars to~10.5, M31, M33, M41 (Beehive cluster), Jupiter setting at 248*, zodicial
light (@~240* - 300*) and about 13 jet trails.
Light pollution data in the form of Total
Sky Brightness and Net Light Pollution is currently being reduced and published
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, that should have a right to see the parks in their natural state.
