How do you know if the orientation of the polar scope is level?
WebAug 21, 2024 · We know that 1 deg = 60 arcminutes so: 1 deg/60 arcminute = 60 arcminute/1 degree By using some simple dimensional analysis, we can set up and solve: 345.6 deg * (60 arcminute/1 deg) => 345.6 deg * (60 arcminute/ 1 deg) = 20736 arcminutes So we can say that 96% of 360 deg is equal to 20736 arcminutes.

Keep reading to learn more about each unit of measure. What is a Circle? A circle is the equivalent of 1 revolution around a circle, or 360°. The average apparent diameter of the full Moon is about 31 arcminutes, or 0.52°. One arcminute is the approximate resolution of the human eye.
