χ1 Hydrae

With beta Crt at the top of your field of view, you'll see two fifth-magnitude stars at the bottom of your glasses: binoculars.

The brighter of these, to the west, is Chi1 Hydrae, a fifth-magnitude binary with a similar companion which makes a complete revolution every 7.4 years, which means that the separation is never more than 0.1".

Now placing chi1 at the northwest corner of your field of vision, move two binocular fields southeast; xi Hydrae will be on your northwestern edge while beta Hydrae will be on your southeastern: binoculars.
