Description A good name for this bright, small but fascinating open cluster
would be the XY cluster because the the brighter members of the cluster are
arranged as the two letters, even the gap between the letters is correct.
This appearance is very striking in the telescope but less obvious in the
photograph on the SEDS NGC website. The cluster contains some bright stars
giving a jewel like impression. It is an object well worth a look for its
curious appearance and beauty.
NGC2169 forms the vertex of a right angle triangle with Xi and Nu Orionis as
hypotenuse.
