This one is easy to locate by aiming straight along the
two iota Sco stars. From i1 Sco through i2 Sco we took a line east to the
first two brightest stars of Mv 6-7. The target was the brightest one,
which turned out to be a most satisfying pair easily separated by about
3 arc". The companion is fainter and it was difficult to make out its colour.
The Brandon eyepiece with the Questars was better than the Celestron Ultima
in resolving colours and contrast.
Observed Colours: primary orange-yellow companion pale (yellow-white?) |

These easily-split little gems are Yellowish white and
Deep blue in a very rich field. An equally delightful binocular pair lie
close to the south.
Ambience: A very puzzling sky tonight. Although a lot of wind movement coming in gusts and dropping temperatures, seeing was very impressive at times. Soon long chains of very light Cirrus cloud dimmed fainter objects. I encountered oodles of faint and striking open clusters, making Double Star Hunting a more variable sport than I had ever expected. My improving detective skills in doubles made finding Uranus and Neptune a breeze. The cat, sprawled in front of the fire, declines to comment. |
