Astronomers use a variety of instruments to measure the distance of stars, including parallax, spectroscopy, and cepheid variable stars. The parallax method involves measuring the slight shift in position of a star when viewed from different locations in Earth's orbit. Spectroscopy analyzes the light emitted by stars to determine their composition and distance. Cepheid variables are stars that pulsate in a regular cycle, allowing astronomers to calculate their distance based on their brightness.
It allows two or more small telescopes to achieve the angular resolution of a much larger telescope. This instrument is credited to Albert A. Michaelson.
A hygrometer is a weather instrument that measures moisture in the atmosphere. It quantifies the amount of water vapor present in the air to provide information about humidity levels.
A spectrometer is used to determine the composition of stars, and how fast they are going relative to Earth.

Stars are observed by means of telescopes, which can have various photographic, spectroscopic, and image enhancement attachments.

I would use a odometer or a trundle wheel
an astrolobeThe instrument you are thinking of is the sextant and it was independently invented by two men at around the same time, John Hadley and Thomas Godfrey.Astrolabe
An absolute altimeter is an instrument which measures vertical distance to the surface below a certain reference point.
Meteorologist observe the hurricane in a close distance with it. Maybe in the future there will be a tool which can measure the speed of the hurricane. :)
This instrument is a balance.
