Subject: Re: Sextant accuracy with short distance to horizon

Dan Allen [mailto:danallen@XXX.XXX] asked:
Simply put, is there a formula or correction to give greater accuracy to
sextant shots taken using a very close horizon? If one knows the exact
distance to the local horizon, can this be applied to the shot to give a
more accurate reading of the angle of a celestial body?
Table 14 in Bowditch gives the correction for a "short horizon". The
"Explanation of Tables" section gives the formula.
