Observation Notes:
After viewing several subtly or elusively colored doubles, this pair was like dynamite! The purest yellow primary with a deep blue secondary snuggled amid a number of fainter stars that sprinkled the high power view. It looks even better at low power with a greater number of field stars and those saturated colors nestled even closer to each other.
