How to Calculate Vertical Distance between Instrument Axis and Lower Vane?
Vertical Distance between Instrument Axis and Lower Vane calculator uses Vertical Distance = Distance between Two Points*tan(Vertical Angle to Lower Vane) to calculate the Vertical Distance, The Vertical Distance between Instrument Axis and Lower Vane formula is defined as the vertical distance above the plane of the instrument axis to the lower vane of the telescope. The formula is used when the observing point is at the elevation and both the angle by vane is at a higher elevation. Vertical Distance is denoted by V symbol.
How to calculate Vertical Distance between Instrument Axis and Lower Vane using this online calculator? To use this online calculator for Vertical Distance between Instrument Axis and Lower Vane, enter Distance between Two Points (D) & Vertical Angle to Lower Vane (θ2) and hit the calculate button. Here is how the Vertical Distance between Instrument Axis and Lower Vane calculation can be explained with given input values -> 12.57121 = 35.5*tan(0.34033920413883).
