A beautiful yellow pair in the eyepiece with about a magnitude difference and 7" separation, 5.6/6.5 7.3", this is a multiple star system with at least five components of which two are easily visible, the primary σ CrB A is an extremely close binary, the C component is 14th magnitude and difficult for small telescopes, C is also close binary, the D component easily visible 100" east listed in WDS is probably not physically associated as it has a different proper motion
