  2. Need • Glare • Light Trespass • Harms wildlife • Wastes government money Vancouver http://farm1.static.flickr.com/101/285102672_4203221326.jpg

  3. Misdirected or misused light Inappropriate application of exterior lighting products Light causing a glow over urban/suburban areas LightPollution http://farm2.static.flickr.com/1293/554194288_965f5494cb.jpg

  4. Spectroscopy • Dispersion of light into component colors • Spectrograph- produces graph of the intensity of light as a function of color or wavelength http://loke.as.arizona.edu/~ckulesa/camp/spectroscopy_intro.html

  5. Stellar Spectroscopy http://cass.ucsd.edu/public/tutorial/Stars.html

  6. The DSS-7 • Spectrograph optimized for the types of spectral observations • Designed to accept F/10 cone of light • Powered by a 9 volt battery http://www.sbig.com/dss7/dss7.htm

  7. The DSS-7 Continued • Sky is blue on a night with a full moon, • Dark skies in light polluted areas are greenish yellow. http://www.sbig.com/dss7/dss7.htm

  8. Literature Review Rosoni, 1997 Spectrum of the night sky at Mound Ekar Observatory Natural sky lines/ artificial lighting http://articles.adsabs.harvard.edu/full/2000MmSAI..71..235R8

  9. Do- Ability • Study done in accessible places • Manhasset, NY • Montauk, NY/ Upstate, NY • Telescope/DSS-7 easily portable • DSS-7 purchased by school in September by supporter adds • $1,595
