NGC5466 is a very dimmed globular cluster in west region of Bootes. It's difficult to catch the globular cluster with finder scopes, you can use a way of searching that firstly find out a bright globular cluster of M3 in Canes Venatici, and next tracing about 5 degrees east from M3. NGC5466 has a visual magnitude of 10, you might need over 4 inch telescopes to detect it clearly. The globular has fairly sparse stellar density; long exposed films can easily resolve member stars around central region. This star field is very far from the Milky Way, and a distance of the globular is estimated about 47 thousand light years. The globular cluster is positioned apart from the galactic disk, to say, lying at a remote region of the Galaxy.
