situation: my character goes to work in a magical store/home(the business is run from the front parlour), located in New York City (Greenwich, I think). Some of the decorating changes automatically with the seasons, ie the trees printed on the hallway wallpaper have their leaves turn, fall, and grow again in the spring. My character's personal room in the house has the ceiling showing the night sky showing directly overhead.
Question: what constellations are highly visible in the night sky above new york city, and do any of them shift position over the course of the year? I basically want my character to look up at the ceiling when she starts work in november, and marvel how easily she can pick out a constellation. Then look up six or seven months later and note that the same constellation has shifted position. Light pollution isn't a factor, and my character's not interested in astronomy at all (though this job might change that), so the more commonly known and easily recognised constellation, the better.
searched: several astronomy books (which only show skymaps for my country), and searched 'constellations+new york city+visible from' - there were a couple of ideas, but nothing specific enough. I found some free skymaps, but they only show the general US continent (nothing specific about NYC), and only this year.
DTA: thanks, everyone! Very helpful, and I think I might see if I can work the Leonid meteor showers in somewhere, too.
