    Polaris isn't so easy!
    From: Jim Thompson
    Date: 2004 Apr 5, 08:05 -0300

    Polaris is my last assignment for the compulsory sight folder in my Power
    Squadron course.  Now that the weather is starting to improve a bit (still
    doggone chilly at twilight, with ice on the horizon), I am trying to get
    Polaris done with my AstraIIIb sextant.  Given that Polaris was a mainstay
    of navigation for centuries, I assumed that it was easy to shoot.  But I am
    finding it difficult, mainly because Polaris is faint enough that by the
    time it comes out the horizon is getting pretty dark.  The evening horizon
    is hazy this time of year too (warm days, cool sea and evening air), so near
    nautical twilight the horizon is that much harder to find, even with my 2.5x
    telescope.
    
    Natural horizon: What are the tricks that ocean-going navigators used for
    shooting Polaris?
    
    For the backyard: Does Polaris show up in an artifical horizon (pan of oil)?
