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. -- GregR --- On Wed, 5/16/12, Randall Morrowwrote: From: Randall Morrow Subject: [NavList] technique for sighting affect accuracy To: NavList@fer3.com Date: Wednesday, May 16, 2012, 7:35 AM 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.
