Description:
This object was viewed using a 35mm Ultima which yields 11x with a 4.3 degree
field of view.  The four brightest stars form a near equilateral triangle with 
a pair of similar magnitude forming the west point.  Pi appears as a pale
yellow star with a very faint, wide companion.  Another dozen stars are 
scattered about, mostly along the sides of the triangle.  There is no
centralization.  A lovely grouping.
