Delta Orionis (Mintaka: "The Belt") forms the left end of Orion's belt (or right-most of the three central stars as we look at them). The three stars of the belt follow the Greek alphabet: delta, epsilon, zeta, and are best viewed in binoculars as all three nicely fit in the same field of view: binoculars.
Delta is a fine binocular binary (BU 558) of a white primary and blue companion, AC: 2.4, 6.8; 0º, 52.4".
Epsilon (Alnilam - The Belt of Pearls), the central star of the belt, is a supergiant surrounded by a wispy nebulosity which generally permeates through the entire constellation.
Zeta (Alnitak, - The Girdle) is very similar to Epsilon, except that this star is a very fine triple system (Struve 774):
Half a degree south of zeta is the famous ‘Horsehead Nebula’, the best representative of a dark nebula. It takes long exposure photos to bring out the famous features; it's invisible in telescopes.
South of the belt are three oustanding binaries, two of which are significant multiple star systems.
Eta Orionis is a fine telescopic double of two white stars: 3.6, 4.9; 77º, 1.8".
Sigma Orionis is a vast multiple system (BU1032) of which the first five are readily accessible—discounting the closeness of B:
When viewing sigma, it is only natural to find this little gem of white stars 3.5' south of sigma: Struve 761, also a multiple system:
