They help you see wide ranges of the sky. Use binoculars before the telescope. You can look at the moon or a certain direction (example: northeast) over time, see what happens, and exactly one year later look to that same direction at the stars you looked at before and you can see what time of year they come back. You can also see what direction they go in all year round.

What instrument used for calculating longitude at sea?
Historically, latitude was always measured with the sextant, and longitude with the chronograph (clock). Nowadays, it's all GPS. ------------------- The "sextant", from the latin word for "six", is one-sixth of a circle, and is the primary tool used in celestial navigation. However, before the sextant came into widespread use, the "quadrant" of a quarter-circle and the later "octant", an eighth of a circle, were used.
Who would use a binocular?
binocculars are a tool that scientists can use to help them see things that are far away.
How do use the navigation system in 2011 Buick Lacrosse?
hit the navigation button and program it
What two-word term do astronomers use to designate the half of the celestial sphere which is south of the celestial Equator?
The Southern Hemisphere
What are the differences between a monocular dissect and binocular microscope?
A monocular microscope has only one eyepiece while a binocular microscope has two eyepieces with different lenses. Binocular microscopes are more popular today than the monocular microscope for professional use. To learn more about microscopes and its uses visit the website in the link below.

What system of navigation in which a navigator finds positions of measure would christopher columbus use?
Celestial navigation or the use of the sun, the moon and stars."Celestial navigation is the use of angular measurements (sights) between celestial bodies and the visible horizon to locate one's position on the globe, on land as well as at sea. At a given time, any celestial body is located directly over one point on the Earth's surface. The latitude and longitude of that point is known as the celestial body's geographic position (GP), the location of which can be determined from tables in the Nautical or Air Almanac for that year."
What did Sir Robert Falcon Scott use to navigate?
Navigation technologies in the age of Heroic Exploration included sextants, theodolites and other celestial navigation tools.
Who uses a Chronometer?
There are so many people who use a chronometer. People who work in the marine use it for celestial navigation among others.
What was the use of the celestial navigation?
Before proper maps, gps and similar, it was used to find the way around the globe.
Where can you learn about celestial navaigation?
Join the U.S. Navy; I believe they still teach celestial navigation. I used to TEACH cel nav for the Navy. However, there isn't a whole lot of call for celestial navigation; a $99 GPS is faster, WAY more accurate, and much easier to use. Add a backpacker's solar powered battery charger, and you're ready to go. The basic books on celestial navigation are Dutton's Nautical Navigation, and Bowditch's American Practical Navigator, which is available online at the link below. Both of these have been the standard reference materials for over 100 years, which is about how long it has been since celestial navigation has changed any. "Navigation is easy. If it wasn't, they wouldn't be able to teach it to Sailors." From James Lawrence, fisherman under sail, Sailing Barge skipper and Sailmaker from Brightlingsea ,Essex, England.
What is a navigation system which is not an inertial navigation system and how does it work?
Celestial navigation, also known as astronavigation (you measure angles of celestial objects with a sextant)Radio direction finding (you use a directional radio antenna to determine direction of transmitter)Non-directional beaconVHF omnidirectional range (VOR)Lorenz beam (this is a beam following system)Low frequency radio rangeGeeLOng-range Aid to Navigation, LORAN (hyperbolic navigation system using pairs of transmitters)LORAN-C (improved version of LORAN)Decca Navigator SystemOmegaAlphaetc.
What scientific discoveries improved navigation and overseas exploration?
An astrolobe which is an instrument that measured the position of the stars , and the magnetic compass helped determine the ships approximate location.
How do you use the word truer in a sentence?
He never had a truer friend than his sergeant in the army. GPS systems can provide a truer basis for locating positions than celestial navigation.
Why is Lockheed Martin significant in the search and navigation instrument industry?
Lockheed Martin produces navigation instruments for land, sea, and air use. In 2002 the company reported annual sales of $26.6 billion and employed 125,000 workers.
Why do sailors use stars back in the old days?
It is called "Celestial Navigation", and was a method of finding your way from Point A to Point B across the vast and featureless ocean by using positions of known stars.

What is Astronavigation?
Celestial navigation, also known as astronavigation, is the ancient art and science of position fixing that enables a navigator to transition through a space without having to rely on estimated calculations, or dead reckoning, to know his or her position. Celestial navigation uses "sights," or angular measurements taken between a celestial body (the sun, the moon, a planet or a star) and the visible horizon. The sun is most commonly used, but navigators can also use the moon, a planet or one of 57 navigational stars whose coordinates are tabulated in the Nautical Almanacand Air Almanacs.
