The "dog's spot" cluster (my name :>) is a stunning
object in telescopes at lower latitudes. From this
relatively northern spot with 10x50 binos, it was a
good-sized hazy blur with 7 stars clearly resolved,
and none seen intermittently. This may indicate that
the magnitude distribution in this cluster consists
of a "high hump" of brighter stars (7), followed by
primarily fainter stars. Or it may just mean this
cluster's beauty is reserved for tropical vacations.
