Sky darkness: 4.5 due  moon <Limiting magnitude> 
Telescope: Celestron C8
Eyepieces: DX-8263SL video camera at 2x and 3x
Magnification: app. 666x, 1000x		 Difficult close pair in this poor seeing.  Used 3x to split this one, but only resolved itself when 35 hand-picked frames were stacked out of 45 Mbytes of data. Both appear blue in color and virtually equal in magnitude. Measured, somewhat poorly, 1.38 sec at 155.1 deg PA.
