Transparency: poor
Location of site: Silverdale WA, USA
47N 123W
Site classification: suburb-rural
Conditions: temp 40F, damp
Sky darkness: 4.5 due  moon <Limiting magnitude> 
Telescope: Celestron C8
Eyepieces: not used
Additional: DX-8263SL video camera at prime focus and 3x
Magnification: app. 333x, 1000x
 		 Difficult dim target viewed on the 10th with 3x magnification and had to integrate the camera x12 to get enough photons to show an image at this magnification. Faintly white to yellow-white stars of equal magnitude. Measurements: 1.55 sec at 208.9 deg PA.

4X Telemate with 2X Zoom for overall of 8X
   		 The video camera is black and white so no color can be noted. This double consists of two components almost equal in magnitude but with magintudes around 10 which is the double with the dimest components but the video camera picked up the pair very well. Close split noted on laptop screen. The final result is an average of five measurements. Theta = 215.6º and rho = 1.3"
