How to know how high the dome is

Make an inclinometer:

Get the altitude of the north star as shown.

Now find out your distance from the north pole by going to bing, right click to stick a pushpin directly above your location close to the top edge, right click again and click on measure distance. Drag the line down and read the miles.

We know that the north star is directly above the north pole in all models, right? So that forms a right triangle on FE with one side equal your distance from north pole, a 90 degree angle, and whatever your inclinometer indicated for elevation of north star.

Use a triangle calculator and you know the altitude of the north star, right?
