We went out Saturday night to see Comet NEOWISE. According to
Space.com, the comet "is delighting skywatchers around the Northern Hemisphere." I'm here to say, "delighting" is an overstatement. At least if you are in a city. Even on a clear night, in a location with no nearby lights, there's enough ambient light pollution to make it hard to do much star-gazing of any kind. Because the comet was low on the horizon, that ambient light pollution is even more of a problem. From Richardson, Plano is kind of bright. And Comet NEOWISE was hanging low over Plano.
