Cities are the bane of the amateur astronomer.  Light pollution continues to grow at an astonishing rate as our cities increase in size and population.  That doesn’t mean astronomy is impossible, just more challenging.  The use of filters designed specifically to quench low pressure sodium and mercury vapor lights has gone a long way.  Enjoy the days of these ionized lamp because they are coming to an end.   I’ve begun to see the impact of LED lighting in my own back yard.  These next few years will likely be the last I’ll be able to capture nebulae from inside the city so I better enjoy it while I can.
