But anyways here's my results. I am not as Marxist, and especially not as anarchist, as these results seem to belie. I am certainly far more socialist in overall beliefs than capitalist, sure, but not like this.

Sextants were first developed with wider arcs for calculating longitude from lunar observations, and they replaced octants by the second half of the 18th century.

Older aircraft sextants had two visual paths, one standard and the other designed for use in open-cockpit aircraft that let one view from directly over the sextant in one's lap.
More modern aircraft sextants were periscopic with only a small projection above the fuselage. With these, the navigator pre-computed their sight and then noted the difference in observed versus predicted height of the body to determine their position.
A sight or measure of the angle between the sun , a star , or a planet , and the horizon is done with the 'star telescope ' fitted to the sextant using a visible horizon.
On a vessel at sea even on misty days a sight may be done from a low height above the water to give a more definite, better horizon.
Navigators hold the sextant by its handle in the right hand, avoiding touching the arc with the fingers. For a sun sight, a filter is used to overcome the glare such as "shades" covering both index mirror and the horizon mirror designed to prevent eye damage.
By setting the index bar to zero, the sun can be viewed through the telescope. Releasing the index bar either by releasing a clamping screw, or on modern instruments, using the quick-release button , the image of the sun can be brought down to about the level of the horizon.
It is necessary to flip back the horizon mirror shade to be able to see the horizon, and then the fine adjustment screw on the end of the index bar is turned until the bottom curve the lower limb of the sun just touches the horizon.
The angle of the sight is then read from the scale on the arc, making use of the micrometer or vernier scale provided. The exact time of the sight must also be noted simultaneously, and the height of the eye above sea-level recorded.
An alternative method is to estimate the current altitude angle of the sun from navigation tables, then set the index bar to that angle on the arc, apply suitable shades only to the index mirror, and point the instrument directly at the horizon, sweeping it from side to side until a flash of the sun's rays are seen in the telescope.
Fine adjustments are then made as above. This method is less likely to be successful for sighting stars and planets.
Star and planet sights are normally taken during nautical twilight at dawn or dusk , while both the heavenly bodies and the sea horizon are visible.
There is no need to use shades or to distinguish the lower limb as the body appears as a mere point in the telescope. The moon can be sighted, but it appears to move very fast, appears to have different sizes at different times, and sometimes only the lower or upper limb can be distinguished due to its phase.
After a sight is taken, it is reduced to a position by looking at several mathematical procedures. The simplest sight reduction is to draw the equal-altitude circle of the sighted celestial object on a globe.
The intersection of that circle with a dead-reckoning track, or another sighting, gives a more precise location. Sextants can be used very accurately to measure other visible angles, for example between one heavenly body and another and between landmarks ashore.
Used horizontally, a sextant can measure the apparent angle between two landmarks such as a lighthouse and a church spire, which can then be used to find the distance off or out to sea provided the distance between the two landmarks is known.
Used vertically, a measurement of the angle between the lantern of a lighthouse of known height and the sea level at its base can also be used for distance off.
Due to the sensitivity of the instrument it is easy to knock the mirrors out of adjustment. For this reason a sextant should be checked frequently for errors and adjusted accordingly.
There are four errors that can be adjusted by the navigator, and they should be removed in the following order. After a year interregnum, the U.
Navy began training again in the sextant as back-up navigational devices as instructed by 30th Chief of Naval Operations inasmuch as it does not rely on electrical systems.
