An azimuth alignment system for an underground azimuth alignable device, the azimuth alignment system including (a) an underground unit including two spaced linear light sensitive articles on an upper face thereof, each of the light sensitive articles including a row of miniature light sensitive elements, the underground unit being connectable in a known positional relation to the underground azimuth alignable device; and (b) an aboveground azimuth alignable telescope device having a longitudinal axis, the telescope device including an aboveground unit, the aboveground unit including at least one light source for generating at least one light beam being detectable by the miniature light sensitive elements of the light sensitive articles, each of the light sources being positioned in a known relation with respect to the longitudinal axis of the telescope device, such that by aligning the telescope device in a desired azimuth and illuminating the light sensitive articles of the underground unit, a deviation of the underground unit and therefore of the underground azimuth alignable device from the desired azimuth is calculable and therefore correctable.
