Checked things out and found that the Camera cable was wound twice around the bench, probably as a strain-relief measure, but that was wound quite tight. I pulled up about 3-feet of cable and loosened the windings. Sould handle a day's ('til sunset) rotation. COMMENT: Sat Aug 27 00:22:34 GMT 1994 Ending observations.
