... The mount is also adjustable so you can orient the axis of rotation to make it parallel with the Earth's axis of rotation (see the section on Polar Alignment). ... Locate the opening in the equatorial mount on the DEC axis. ... To mount the telescope tube: 1. ... ADJUSTING THE MOUNT FOR POLAR ALIGNMENT In order for the clock drive to track accurately, the telescope's axis of rotation must be parallel to the Earth's axis of rotation, a process known as polar alignment. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
