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 is wide, and easily split at low power. 81x offered the
best view because it reduced the glare from the stars and made it
easier to see colors. One star appeared yellow, and its companion was
yellow-orange. If the stars were closer together, this pair would look
nicer, but still, the colors were nice.
