PurposePurpose
http://imgsrc.hubblesite.org/hu/db/images/hs-2002-10-c-web.jpg
To examine the difference between the pollution of light inManhasset, NY as opposed to the lack of pollution inMontauk, NY.
HypothesisHypothesis
•Null Hypothesis: no differencebetween the light pollution in both areas
•Alternate Hypothesis: light pollutionwill be greater in Manhasset than inMontauk

MethodologyMethodology
Light Pollution Measured by the DSS-7
Control: sky measured by DSS-7 inMontauk, NY
Variable: sky measured DSS-7 inManhasset, NY
Procedure
Spectrograph attached to the CCDimager, many images taken toexamine types of light pollutants,images processed and stackedusing Maxim DL software
Measurement
Measured once a week in Montaukand imaged, measured once a weekin Manhasset and imaged over 7months
Analysis
Graph/map of data collected
Amounts vs. types of light pollutionanalyzed
