    Re: Early sextants & Lunars...

    <<Bill Morris has called the Heath Hezzanith as *the finest sextant ever* made.>>

    Not quite, Brad. I described "Heath and Company's best vernier
    sextant" here: http://sextantbook.com/2011/12/ ,but didn't go as far as to call it the finest ever made. That honour probably has to go to the Soviet era SNO-T. There is probably nothing to choose between the turn-of-the-century vernier sextants made by Heath and Co, Hughes and Son and C Plath.

    Most sextants of the time are divided to read to 10 seconds, but it is very difficult to decide which pair or even 3 or 4 pairs of lines coincide when reading the verniers. I look either side to see which two pairs just do _not_ coincide and choose the middle value between them.
