I always like looking at this double. Although I could easily
find the faint companion at 49x, the best view was at 81x. At
this magnification, the primary is yellow-shite and the
companion is pale blue. It reminded me of what the Earth and
Sun might look like from perhaps a moon of Saturn.

[Editor's Note from Lew: What a stunning comparison! I may
have to steal that one for public observing events... :) ]
