Star: Struve 1935
Date & Time: 6 May 2003 11 pm to 1 am
Seeing: 4-5  <1-10 Seeing Scale (10 best)>. 
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, 6x
Magnification: app. 333x, 1000x and 2000x		 One attempt at one of those dim project stars. Took quite a long time to find even with settings circles and the fact that this star is near eta CrB. Just too faint for the 2 inch finder in this poor transparency. Finally turned off the red reticle illumination and found it. WDS list the mags at 9.91 and 10.19, even fainter than the project list. Had to go to prime focus to get enough light on the CCD. Measured, 8.73 sec at 290 deg PA.

 The video camera is black and white so no color can be noted. Nice fairly close double of semi-bright components. The final result is an average of five measurements. Theta = 289.2º and rho = 8.67"
