    Re: Sextant platform for lunars
    From: David Pike

    Not exactly lunars, but Roald Amundsen states towards the end of Ch12 of ‘The South Pole’ that prior to their series of hourly observations at the pole they built two pillars of snow, one to place the artificial horizon on and one to rest the sextant on when not in use. DaveP

    Perhaps I should have added that having fiddled around with my artificial horizon last winter (at 53N not 90S) at low angles, e.g. the order of HC = 23°, you really need a raised AH, or you end up either a long way behind the AH, which makes getting everything lined up difficult, or with very cold knees or derriere.  DaveP
