    Re: Consistent error question

    Marty,

    Please tell us about your sextant. How have you adjusted your index and horizon mirrors? How have you determined index error? What sight reduction method have you used ? I will assume that index error was corrected first then dividing by 2 to get Hs and finally subtracting the refraction correction to get Ho. Intercepts of 1' or better are good artificial horizon results if using a properly adjusted metal sextant .
