So, you measured the altitude of a celestial body to within three degrees by using... a lawn chair. Why do navigators waste so much money on sextants, I wonder?

Although you claim to be replying to me, you still haven't answered my question: What instrument did you use? If you did not use an instrument, your observation is meaningless. You cannot observe an object at the zenith while standing upright. Unless you are a mutant, your neck is incapable of bending at a ninety degree angle. That is why objects above (around) sixty degrees elevation appear to be "overhead."
I guess you've never heard of lawn chairs. They can be extended and flattened so that they are perpendicular to the zenith (90 degrees or, more commonly - directly overhead.) (I was out waiting for the libration event lol.) I'm asking myself, at this moment, what's wrong with this picture? And I'm answering myself saying that I think I've stumbled into a circus.
Why is this significant: The Pleiades, the moon, the sun and zodiac stars all travel within a certain area - the ecliptic - from our earth point of view. At mid-latitudes, like 38 degrees N, they should never appear directly overhead.
Put simply, the ecliptic is the plane of Earth's orbit around the Sun.
Lawn chair...lol.
You are mistaken. Just as you are about the direction in which the Mauna Kea webcam is aimed.
Last night, for me, the moon was within 2-3 degrees of directly overhead.
Anyway, the lawnchair would be your first step. Go outside at night; get the lawn chair perpendicular to the sky; observe.
How do you calibrate your lawn chair?

lol...well if it doesn't look flat to you I guess you could use a bubble level or, fancier, a laser level.
Come on. Where.....is.......it?
You might find something laying around, a loose marble perhaps, that could be used to help level your lawn chair astronomer kit.
It's behind the Sun, 30 degrees below the Ecliptic and a little beyond Pluto.
I see by your post that you are not familiar with the lawn chair.
A lawn chair is something that anyone in the southern U.S. is familiar with. So I'm going to assume that you're not from here.
At 38 N Lat I'm no damn yankee. The last time I saw the Moon it was nowhere near directly overhead.
In 832 AD, a Pictish army under King Angus MacFergus, High King of Alba, along with a force of Scots under Eochaidh, King of Dalriada (and grandfather of Kenneth MacAlpin), was battling a Northumbrian force in Lothian for control of that region. The night before battle, Saint Andrew reportedly appeared to Angus in a vision, and on the field of battle the next day, a saltire, or x-shaped cross, similar to the one that Saint Andrew was crucified on, appeared in the sky, encouraging the Picts and Scots in their fight and causing the Northumbrians to flee the field, after their leader, Athelstan, was killed. The site of the battle was and still is known as Athelstanford, or "the ford of Athelstan". The colours of the flag are supposed to represent the white clouds and the azure colour of the sky.
And tThat's all tThere is about tThat.

Can we get a jpeg of the emeffer?

Determined to within three degrees by what sort of instrument?
