Purpose To examine the difference between the pollution of light in Manhasset, NY as opposed to the lack of pollution in Montauk, NY.

Hypothesis Null Hypothesis: no difference between the light pollution in both areas Alternate Hypothesis: light pollution will be greater in Manhasset than in Montauk

Methodology Light Pollution Measured by the DSS-7 Control: sky measured by DSS-7 in Montauk, NY Variable: sky measured DSS-7 in Manhasset, NY Procedure Measured once a week in Montauk and imaged, measured once a week in Manhasset and imaged over 7 months Measurement Night light sources as observation points, visibility analysis Analysis Graph/map of data collected Amounts vs. types of light pollution analyzed

Study done in accessible places –Manhasset, NY –Montauk, NY/ Upstate, NY CCD imager/DSS-7 easily portable Software downloaded for free off SBIG website/astronomy coolwiki Do-Ability
