I am a fan of Star Walk, but, as I see you represent the Star Walk App would like to take this opportunity to get your attention on a matter I posted before:
While in New York City, the "home location" is inaccurately reported as West New York, N.J. This is 8 miles away. While in East Hampton N.Y, the "home location" is reported as a city in Connecticut (I don't remember the city) that is 130 miles away from the actual location. With the built in gps features of the Ipad, and other apps reporting my location accurately, down to the street number, this inaccuracy makes no sense at all.
