NGC 869/884 - Double Cluster




The Double Cluster is visible from rural areas as as a faint patch between the constellations Cassiopeia and Perseus.  One of the finest objects accessible to small telescopes, the two clusters glitter as a pair of matched celestial jewels.  Several Red Giant stars can be identified in the above photograph.
