Realistic periscope magnification
Fix periscope magnification settings. Allows you to use an obvious equation to determine the distance to a target.
Divide the height of the ship by the centiradians, and multiply by 4 if the periscope is zoomed in.
The periscope has a milliradian reticle (like original German attack periscope type StaSR C/2), so to be precise, to calculate the distance in 1.5x mode , the following formula is used
Mast height in meters * 1000 / visual height in milliradians = distance in meters.
in 6x mode obtained value in meters must be multiplied by 4* .
*Because the magnification at 6x is greater than 1.5x by a factor of 4, and the periscope reticle (in real life the same) is normalized to 1.5x
