The late Janet Mattei, director of the American Association of Variable Star Observers, once gave me this good advice that I would like to pass along: “Even if your observing site isn’t the best, make the best of your observing site.” Sure, we would all like to have a dark sky right outside our backdoors. But that isn’t always possible.
The odds say 5 out of 7 clear nights take place during the week. Rather than turn your back on what you do have, waiting instead for a clear weekend night when you can escape the city for the country, make the best of what you have at hand. You just might be surprised at what can be seen with a little diligence and perseverance.
