Star: Struve 577
Date & Time: 26 November 2002,
9pm to 11pm
Seeing: 5 <1-10 Seeing Scale (10 best)>
Transparency:  fair, some hi clouds
Location: Silverdale WA USA, 47N, 123W
Site classification: Suburb-rural
Sky darkness: 5.5 <Limiting magnitude>
Conditions: No wind, some dew, temp 32º F
Telescope: Celestron C8
Eyepieces: not used, video only
Magnification: ---
Additional: PC164C video camera pf, 3x, 6x teleconverters
Difficult object due to the closeness and faint magnitude. This was elongated using the 3x magnification, and split at 6x, but this is near the limit of an 8 inch with this video camera setup. Measurements: separation 0.871 sec at 358.9 deg PA.

After finding this double with low power (70x), situated in a moderate field Idirectly switched to 280x. The seeing allowed for an on-and-off separation. Formoments the separation was obvious and easy to see, other moments onlyelongation remained.The pair is a bit too faint to give a nice view at this power, especially now that the images are smeared out quite a bit.
