|Sigma Orionis is an interesting multiple binary, some of whose components can be enjoyed with binoculars.
Starting at zeta Orionis, in the same field of view to the southwest
is sigma Orionis (3.7 combined visual magnitude): binoculars.
Sigma is a multiple binary with one very close companion and two wider ones. While a small telecope would be of better use to fully enjoy the spectacle, its brightest companion should be visible in binoculars.
The bluish-white primary (3.7) star has a bluish companion (6.7 separation 42" at PA 61º) which you might be able to resolve, and a reddish one (6.9, PA 84º and separation 12.9") which will require a scope.
