Thus the line of collimation of the telescope was placed at right angles to the surface of the mirror.
The collimation error was found by reversing the instrument and using a terrestrial mark, the azimuth error by star observations.
Was nearly half the day in adjusting the line of collimation in the telescopic sights of my theodolite.
The objective is mounted in the most approved manner and is provided with adjustment for collimation.
The axial center line of the lens, or the line of collimation, is then in adjustment with the level.
