Place δ Cas (Ruchbah) at the NE of the field and the 5th magnitude φ Cas will lie diametrically opposite. Centre φ Cas, which is the brightest star of this cluster, although it is not actually a member of it.
What You Should See:
is near the top of my list of star-party objects. The two brightest stars, φ Cas and its nearby 7th magnitude companion appear as the glowing eyes at the SE of a stick-man asterism with outstretched arms, which, just detectable at ×37, gives this cluster one of its common names.
