    Re: Where the Bing are we?

    I’m pretty sure we’re looking at The Feathers outcrop from the south, which is at about 47°N, so why is the cut of the stars against the ridge 45° and not 43° or 47°?  43° I think it should be.  Could it be the fact that Polaris is not above the centre of the picture?  The camera appears to be pointing at about 330°.  If you suspend a stick in space, its tilt is least when you view it from a direction perpendicular to its plane of suspension.  As you move from side to side its tilt appears to get greater, because its height remains the same, but its apparent width reduces, so that’s no help.  We want the cut to reduce to 43°.  What about height difference?  If you raised the camera to the height of the ridge, you’d see the stars lower down, so that would help.  It might just be Bing or my laptop stretching the photo horizontally, or it might just be my bad measuring.  Any ideas?  DaveP
