The instrument consists of three rings, the meridien, the equator, and the declination ring. It may be considered to be a simplified, portable armillary sphere , or a more complex form of astrolabe . The Rings The meridian astronomy meridian ring, when in use, occupies a plane with one axis running north and south, and the other vertical. A sliding suspension shackle is attached to the top of this ring, from which the whole device can be suspended. When properly used, this points to the latitude at which the instrument is being used. This ring can function as the gnomon , when the rings are used as a sundial . The equatorial ring occupies a plane parallel to the celestial equator, at right angles to the meridian. Often equipped with a graduated scale, it can be used to measure right ascension . The declination ring is moveable, and rotates on pivots set in the meridian ring. An imaginary line connecting these pivots is parallel to the Earth s axis. This ring is often equipped with vanes and pinholes for use as the alidade of a dioptra .

Refimprove date July 2010 Expert subject date August 2010 Astronomical spectroscopy is the technique of spectroscopy used in astronomy . The object of study is the electromagnetic spectrum spectrum of electromagnetic radiation , including visible light, which radiant energy radiates from star s and other celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, but also their motion by Doppler shift measurements. Stars Astronomical spectroscopy began with Isaac Newton s initial observations of the light of the Sun , dispersed by a triangular prism optics prism . He saw a rainbow of colour, and may even have seen absorption line s. Citation needed date August 2010 These dark bands which appear throughout the solar spectrum were first described in detail by Joseph von Fraunhofer .

Image 2dfgrs.png right thumb 300px Rendering of the 2dFGRS data In astronomy , a redshift survey , or galaxy survey , is a astronomical surveys survey of a section of the sky to measure the redshift of astronomical objects. Using Hubble s law , the redshift can be used to calculate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter within a field of the sky. These observations are used to measure properties of the Large scale structure of the cosmos large scale structure of the universe. The Great Wall astronomy Great Wall , a vast conglomeration of galaxies over 500 million light years wide, provides a dramatic example of a large scale structure that redshift surveys can detect. The first redshift survey was the CfA Redshift Survey , started in 1977 with the initial data collection completed in 1982. The most notable, recent and low redshift surveys are the 2dF Galaxy Redshift Survey , Sloan Digital Sky Survey and the Galaxy And Mass Assembly survey . At high redshift there exist the DEEP2 Redshift Survey and the VIMOS VLT Deep Survey VVDS . Because of the demands on observing time required to obtain spectroscopic redshifts i.e., true redshifts measured by velocity , it has become commonplace to use photometric redshift s, http astrowww.phys.uvic.ca grads gwyn pz index.html based on brightness. Such redshifts can be used in surveys and to find the space distribution of galaxies, provided the galaxy types are well known, but, obviously they cannot be used to define points on the Hubble curve, because of circular reasoning.
