Description:
With the nearly first quarter Moon high overhead as twilight neared an
end, I knew that my Herschel galaxies were out of the question from my
back yard.  So instead, I gathered up the last couple of issues of
Sky&Telescope to see what objects were featured. As it turned out,
most of the observing articles were about double stars. In the
moonlight, doubles seemed the best course to take, so I thought it was
fitting. I hand-picked several of those listed that I either hadn't
seen yet, or else I hadn't visited in quite a while. I began in Corona
Borealis, but the glare of the Moon in that region of sky made me
retreat Draco, the land of the Dragon.

This double could barely be split at 49x, and the best view was at
125x.  Both stars appeared white, and one was about a magnitude
fainter. There wasn't anything remarkable about this pair, but it
still was a nice view.
