Stars within 50 Light Years

We are now about 200 light years from Earth viewing a cube a space 100 light years on a side. There are perhaps 1000 stars within that volume -- within about 50 light years of Earth. Many more stars are seen here because we are now including background stars that are far behind the Sun and happen to lie within our field of view. All of the stars from the previous image are now within the small square -- and invisible to our unaided eye. To see any of the Sun's closest neighbors from 200 light years away requires a good telescope and an eye for detail. In these larger volumes of space, only the brighter stars are visible.
