Eta Lupi is a fine binocular double: 3.4, 7.8 magnitudes, 20º with a separation of 15". The difference in magnitude may make it difficult to resolve except with larger binoculars.

To find the star begin at Antares and move due south two binocular fields (where two bright stars, H and N Sco will be centred) then move one binocular field to the southwest: binoculars.

Alternatively, you can starhop from alpha-beta-epsilon-gamma then move one binocular field northeast of gamma.
