Date & Time: 8th September 2001. 2045UT
Seeing: 3-4 <1-10 Seeing Scale (10 best)>
Location of site: Near Halifax West Yorkshire, England.
Site classification: Suburban
Conditions: Clear sky, fresh NNW'ly breeze
Temperature: 8C 
Sky darkness: 4.8 <Limiting magnitude>
Telescope: Orion Optics UK GX250 10"  f4.8 Newtonian on Vixen GP mount.
Eyepieces: 20mm Plossl, 9mm Ortho, 7.5mm Plossl
Magnification: x60, x133, x160
The poor seeing made this one very difficult. There was evidence of elongation at x133 and, just perhaps, a split at x160, but the image was 'boiling' badly. Higher powers were hopeless tonight.

This could not be counted as split and I need to return.

Seeing: so-so
Location of site: Killeen, TX 
Site classification: Suburban 
Sky darkness: 4 <Limiting magnitude>
Telescope: 8" SCT 
Magnification: 80x, 200x, 165x (CMG)
 
A tight pair, I was just barely able to split this at high power. Color seemed to be white, and this looked sort of like a snowman with just the thinnest sliver of black between the two. At low power it was elongated a bit.

Magnification used: 67x, 160x, 320x
              
Only elongated at 67x, and a figure-of-eight at 160x. Needs 320x to split cleanly. Two stars of equal brightness, both are off-white.
