This cluster has an interesting appearance in the 10-inch. This is presented in the sketch at left, which was drawn at 82X. 7th magnitude GSC 2906:152, positioned just south of center, is the brightest star in the field and lays at NGC 1664's outer edge. Sixteen arc minutes to the north, a triangle asterism of 11th magnitude GSC stars marks the opposite boundary of the cluster. In-between, a Y-shaped scatter of about 30 stars dot the field. The scene is framed by 18 additional stars in my drawing. 1664 resides 2.0 west of 3.0 magnitude Alnaz, Epsilon (7) Aurigae, just across the border from Perseus.
