Thanks Wavytone for your input. But I cannot credit Castor as being a better example. I am speaking particularly of observable triple doubles. Castor does not fall in this category. There are certainly many other sextuple systems out there, most if not all will be unobservable in an amateur telescope, with perhaps the notable example of theta Orion - which does not fit the category "triple double"

I should add that this "triple double" is not a bound system in any way, merely an optical gem of the sky.
