Telescope: Meade 16 LX200GPS
Eyepieces: not used
Imaging: DX8263SL video camera at prime focus
Magnification: app. 600x

 Difficult nutcracker at prime focus, used the camera zoom 2x function to see the pair. Nice color contrast too. Seeing caused this pair to merge most of the time. Measured; 1.32 sec at 344.4 deg PA.

Time: 4:19 UTC
Seeing: Pickering 4
Transparency: Average
Location: New London Township,
PA, US (+39d45m,-75d52m)
Site classification: Suburban/Rural
Conditions: Clear with passing clouds
Sky darkness: Not determined
Telescope: TMB152 f/7.9 Apochromatic Refractor
Mount: Losmandy G-11
Eyepieces: TMB/BO Planetary 4mm
Magnification: 300x

 The AB pair was difficult and was resolved only in the moments of the best seeing. The stars were colored yellow and bluish.  The 13.5-magnitude C components was fairly easy to spot with averted vision. I was a bit surprised at being able to see this star with relative ease from the 5.5-magnitude skies.

Site classification: Rural
Conditions:
Sky darkness: limiting mag = 6
Telescope:
- visual : 120mm refractor used as guidescope 
- imaging : homemade Newton 8", Barlow 3x with tube extender, Audine K400 (sampling 0"32/px) 
Eyepieces: 20mm,7.5mm

I took some series at different exposure times without conviction.
Clearly undersampled (0"32/pixel) to stand out the components and make a
measurement.
