30mm Ultima---------A
classic view of this pair of almost equal magnitude stars. I found it difficult to
determine any definite colour but both appeared to be yellowish. There
were some nice stars in the fov too. 9mm Or------The increased magnification gave a darker sky and two yellowish stars were seen. One appeared to be a slightly deeper shade of yellow than the other. A nice pair of cats eyes. A visual estimate of PA for the slightly fainter star was about 340degrees. Ambience. There is only about 1hr of complete darkness here at this time of the year and this falls at just about the time of packing up ready for work the next morning. There are some large aircraft trails floating by and I notice that some have formed a huge X in the sky. These look weird against the twilight sky. |

A fine and very easy
couple
composed by bright and very comparable stars (extimated magnitude
difference
about 0.1-0.2 mag). These stars are pretty but not excessively distant
and are
both almost pure white. The rings are visible during some rare moments.
Extimated PA about 345 degrees (I'm pretty sure that this pair changed
its
position as my extimated PA is different from the PA on the table).
Fine double
well suited for small telescopes.
