The View through the Theodolite shows a crosshair. The horizontal line of the crosshair corresponds to eye-level at the position of the observer at an altitude of 3,5 m above the lake. As you can see, the horizon raises not to eye-level. About 57 m of the Marriott Hotel at a distance of 38,8 km on a Refraction k = 2,5 are hidden behind the horizon and the eye-level line is at a height of 70 m on the Marriott Hotel.
