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 views in binoculars as all three nicely fit in the same field of view: Binoculars.
Delta is a fine binary with several companions, the brightest of which (companion D) is 0.53" due north (i.e., at a position angle of 360º). It takes at least 10x binoculars to resolve the binary (or of course a small telescope). Eta, at the western edge of your glasses, is also a multiple binary which requires a medium sized telescope to resolve. |
