Bushwick native Kat Troche grew up looking at the stars. A member, these days, of the observing committee of the Amateur Astronomers Association of New York, she’s going to be at the helm of the Association’s latest new sidewalk stargazing location in North Brooklyn. After some back and forth over weather-related delays, the group has settled on a date in mid-May to gather local starwatchers outside the DeKalb Library on Bushwick Avenue. The group will also be hosting a stargazing event earlier in the month in nearby Crown Heights.
