... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...

Villains and Heroes of Lights and Lighting Fixtures . If we are to reduce the effects of light pollution, we must learn about the types, both good and bad, of fixtures used in outdoor lighting. ... In fact, this type of fixture is often chosen for this very reason. ... Although these lamps are not very energy efficient, and they are often found in older, inefficient fixtures that enhance light pollution, they still exist in great abundance in most locations and are still sold by the millions. ...

Eliminating Light Pollution . ... Low Pressure Sodium . ... Low Pressure Sodium bulbs are the most efficant, use the least energy in producing light and have very low running costs. ...
