A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon which is known as the altitude. Making this measurement is known as sighting the object, shooting the object, or taking a sight and it is an essential part of celestial navigation. The angle, and the time when it was measured, can be used to calculate a position line on a nautical or aeronautical chart. A common use of the sextant is to sight the sun at solar noon and to measure the elevation (altitude) angle at night to measure the elevation angle from the horizon plane to Polaris to find one's latitude. Since the sextant can be used to measure the angle between any two objects, it can be held horizontally to measure the angle between any two landmarks which will allow for calculation of a position on a chart. A sextant can also be used to measure the Lunar distance between the moon and another celestial object (e.g., star, planet) in order to determine Greenwich time which is important because it can then be used to determine the longitude.

If you need a 85mm fast prime, there is not a wide choice of M42 lenses. The most famous is the Helios 40 (85mm f/1.5) But this lens is not a low cost item for your DSLR because it is to much hyped. Certainy because of it's vintage(and massive) look.
So the alternative is the Jupiter 9. This short telephoto (85mm) Russian lens is opticaly based on the Carl Zeiss 85 Sonnar. This is a pre-war optical formula.
We can consider it as a fast prime lens because of it's wide aperture (f/2.0)
For portraiture wide opened you will get a very small dept of field (just on eye!)
