Skyscraper Light Pollution

New Skyscraper Causes Tremendous Light Pollution

During the past several months, a new very tall skyscraper is under rapid construction. 

Located due South, it will become one of the tallest in the country, spanning upwards well over 120 floors with seven windows per cardinal side or 28 windows per floor, resulting in 3,360 windows of piercing wide band light pollution spreading outwards like multiple beacons washing across the expanse. 

So far, the skyscraper is still going upwards under construction - each night, all floors and all windows are lit up with high intensity white lighting, in direct violation of city lighting ordinances. 

This completely obliterates the night sky rendering the entire south direction of the sky totally useless for astronomical endeavors. It also casts light directly on telescopes and destroys all night viewing. 

Economics must be very good as the city is also constructing three more skyscrapers in the same region. The observatory is equipping with light filtering accessories and trying out various types to see which can improve the sky in some small way. 

Filtering will include various colors, wide band, narrow band, high contrast, specific cut, pass, polarizing, and various pro derivatives. A filter wheel will hold filters for rotating into the field for rapid test comparisons. Tests will include both visual and astro imaging.

In addition to the filters, the observatory will try out several new telescopic sky viewers to test for any improvements in the night sky.
