    Re: technique for sighting affect accuracy

    Just a thought, but I'm wondering if you get better results shooting with your 
    left eye because that's just what you're used to, and if your right-eye 
    results might improve with some practice (i.e. maybe being able to more 
    accurately position the object on the horizon). Interestingly enough, I shoot 
    the same way even though I do most other things right-handed.
    
    
    If I get time, I'm going to take the sextant down to the beach this weekend 
    and I'll make a note to take some of the shots with my right eye to see if I 
    can draw any meaningful comparisons between them.

    Just some quirky things I noticed lately...
    I normally shoot with my left eye and when I tried using my right eye accuracy 
    decreased somewhat.  Here are some sights and intercepts done on UNSO:
    Saturn 0.1A left eye, 0.9A right eye
    Venus 0.2T left, 1.2 T rightYou can focus a scope to shoot without using your 
    glasses but in my case it decreased accuracy.
    Arcturus 0.3T with glasses, 3.7 without glassesHighe power scope may be 
    problematic on small boats but on land I get more accurate sights.
    Arcturus 3 X scope 1.5T, using 7 X scope 0.0 and 0.2T
    Venus 3 X scope 1.9T, using 7 X scope 0.6T and 0.8TSorry I did not include the 
    raw sight data. It's too early in the AM.
    One more thing: i thoughit would be harder to "find" stars in the 6.5 degree 
    field of view of the 7 X scope but this has not been the case.  On a boat it 
    would be another story.
    Clear skies, Randy
