... about a star through its light, these observations do not give us a reference scale to use to measure their distances. We need to rely on a method that you are actually already familiar with: the parallax of an object. You can see the parallax effect by holding your thumb out at arm's length. View y ...

Reflecting instrument

Reflecting instruments are those that use mirrors to enhance their ability to make measurements. In particular, the use of mirrors permits one to observe two objects simultaneously while measuring the angular distance between the objects. While they are used in many professions, they are primarily associated with celestial navigation, as the need to solve navigation problems, in particular the problem of the longitude, was the primary motivation in their development.
