A Sextant is an instrument used to measure the angle between any two visible object and a Telescope is an instrument that aids in the observation of remote object by collecting electromagnetic radiation.

A sextant would be a type of astrolabe. It has a sighting mechanism that is a small telescope. It does not have a compass in it.
A sextant box is a protective case designed to store and transport a sextant, a navigational instrument used to measure the angle between celestial objects and the horizon. Typically made of durable materials, it ensures the sextant is safeguarded from physical damage and environmental elements. The box often includes compartments for additional accessories, such as a sighting telescope or a polishing cloth. Proper storage in a sextant box helps maintain the accuracy and longevity of the instrument.
The primary tools used in early astronomy were a compass to measure directions, a sextant (or octant) to measure angles in the sky, a watch and a telescope.

When using a sextant, if you see two images of an object, it is typically due to the presence of an optical illusion known as double vision or parallax error. This can occur when the telescope is misaligned or if the observer's eye is not perfectly positioned at the eyepiece. Additionally, atmospheric conditions can cause light to bend, leading to multiple images appearing. Proper alignment and technique can help mitigate this issue.
Four very important instruments are the Human Mind, Mathematics, telescopes like the Hubble and Spectrum Analyzers.

A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths

A sextant is a navigational instrument used to measure the angle between a celestial body (like the sun or stars) and the horizon. It consists of an arc marked in degrees, a movable arm called an index arm, and a telescope for sighting. By aligning the celestial body with the horizon using the index arm, the navigator can read the angle on the arc, which is then used to determine their latitude and longitude based on time of day and celestial charts. The sextant is essential for celestial navigation, especially at sea.
