Date: 6 Feb 2006
Time: 22.15 UT
Seeing: 6-7 <1-10 Seeing Scale (10 best)>
Transparency: --- <1 worst - 10 best>
Location of site: Northwich, Cheshire. UK.
(53° 15' N -2º 33' W).
Site classification: Suburban
Conditions: Crisp cold frost, bright moonlight.
Sky darkness: <Limiting magnitude>
Telescope: 200mm f/6 Newtonian reflector
Mount: Vixen GP
Eyepieces: 30mm Ultima, 9mm Orthoscopic.
Magnification: X40, X133

 9mm Ortho : At first glance this double appeared as two white stars. In moments of steady seeing though, I observed a lovely pair of  the palest yellow and ice blue stars surrounded by stars right on the edge of the fov.
30mm Ultima:  A much better view with more stars in the field. A classic view of a nice double star. HR of 1 for this one. This would probably be a much better view without the strong moonlight.

Scattered thin clouds again.  "clouds, clouds, go away come back some other day"  And I mean day!  Lovely pair of yellow and yellowish white stars.  Double makes a large triangle with two dimmer stars.

 Twin, almost equal blue-white stars, easy split. WDS has a real faint third star listed from one measure in 1913, I did not see it, maybe try again and put a bit of integration into the camera to pull it out of the background. Measurement, AB 19.97 sec at 209.8 deg PA.

 Located at 8:31pm PST. Easily split in the 30mm Ultima I was using as a finder. Went right to the 9mm ortho to maximize enjoyment. This nearly equal pair seemed mostly white with just a hint of blue in the secondary. Lovely.
