What is the primary purpose of the fist method when observing Jupiter?
Answer
To gauge the altitude of the planet above the horizon.
The fist method acts as a practical way to gauge altitude when using coordinate data from digital guides. By holding your arm at full extension and placing your fist against the sky, you can approximate 10 degrees of elevation, as the width of a fist is roughly equivalent to that measurement. This helps translate technical data into a physical, trackable point in the sky.
