For those who have the Navy MK 5 aircraft bubble octant and would like to improve conventional non-bubble observations using the horizon in prism (natural horizon) try presetting the micrometer drum to an even minute then let the body rise or set to horizon tangency. The Navy MK 5 micrometer drum is only graduated every two minutes of arc so it is very easy to get awkward in between readings.
