1. One of the bevel faces has a thin, shiny (stainless?) metal facing added. Is this the face that the dovetail set-screw should press against, or is this face intended intended to be a low friction face on the other side from the set screw, allowing easy balancing?
2. (See picture) Is there any advantage/convention on whether the setscrew should point up or down when mounting the telescope? I'm in Seattle and the sun doesn't get very high in the south... I thought perhaps, since I'm not aiming at the zenith or north, that perhaps orientation #1 was more secure?
