A beautiful star field, too many to count! The eastern-most cluster NGC 884 (chi, at bottom) is slightly dimmer and less compact than the western cluster NGC 869 (eta, at top). Estimate about a 1/2 degree between the two clusters; they lie about 7,500 light years away in the Perseus Arm of the Milky Way galaxy.
