Charlie Stross@isaackuo @nyrath That maximum elevation for the sun is similar to where I live (Scotland) in midwinter. It's a royal pain in the eyeball even with an atmosphere to attenuate it. I suspect a tech solution is desirable: gaze-tracking camera inside helmet plus an occlusive block to get between eyeballs and line-of-sight on the sun, perhaps? (Either an opaque LCD shutter or a physical, motorized sunshade inside the helmet glass.)
