    The Misty Head of Orion (evening)

    Orion's head is composed of the blue giant, magnitude 3.6 star Meissa or
    Lambda Orionis and a pair of magnitude 4 stars Phi1 and Phi2 Orionis. To your unaided eyes, they form a half-degree wide triangle with Meissa on top (celestial north). Binoculars or a low magnification telescope will reveal a pretty sight. A neat line of three stars links Phi1 to Meissa, and a magnitude 5.6 star continues the chain to the north. Altogether, about 20 stars
    scattered across 1.2° of the sky combine to form an open cluster designated Collinder 69 or the Lambda Orionis Cluster. These hot, young siblings are gathered about 1,600 light-years from our sun. Phi2, which shines with a
    golden colour, is an unrelated star in the foreground. Crank up the magnification to split Meissa into a splendid double star. Its orbiting magnitude 5.5 companion is tucked in close to the northeast. Astronomers have been tracking the change in their relative positions since 1779.
