Abstract
A pair of small auxiliary telescopes in the neighbourhood of a telesco pe that utilizes a sodium-laser-guide star are able to provide informa tion about the absolute tip-tilt of the sodium star. The technology in volved is the same as differential seeing monitor techniques, and the coverage obtained by the technique described is of almost the whole sk y.
