What effect does light pollution have on the Observatory?
Light pollution is a concern for any observatory surrounded by encroaching urban development. Richmond Hill’s light pollution by-law was developed because of the David Dunlap Observatory — and without an operational observatory, the Town would have no reason to enforce the by-law. Whenever we set up our small telescopes in schoolyards or city parks to help educate the public, we contend with light pollution. This is nothing new.
