9mm Or------An easy split
at this magnification into
what appeared to be a white and pale orange pair of stars. I have
noticed
that the sky conditions have deteriorated though. 6mm Or------A wider split. The PA of the companion was estimated to be about 320 degrees( visual ). Both stars seemed to be white most of the time with companion a dull orange at times. |

Faint stars are by default white. These stars were faint and white and also a bit difficult at 85x, no doubt owing to the dimness of these stars and the moonlight. | |||
