Alan,
To my last post I should add that light pollution makes only the brighter stars visible in the sky most of the time. But in a clear and crowded star field it would be much easier to shoot the wrong pinpoint of light. I may have missunderstood your question in this regard. But if you shoot the brightest stars, you can still pick its "twin" in the index mirror. Its also a good idea to make a guess at the approximate alitude before you shoot. If your sextant reading is way off the estimate, shoot again. The dimmer the star the more one looks like another.
