I'm sure I'm just doing something dumb, but:
Yildun has a declination of approximately 86.5. This puts it 3.5 degrees from the celestial north pole.
Per the snapshot below, Yildun's azimuth can be as high as 4.17 degrees.
Since the celestial north pole always has an azimuth of 0, wouldn't this put Yildun 4.17 degrees from the pole, contradicting the distance calculated from declination?
What am I missing?
EDIT: I thought I'd figured this out:
On Earth, one degree of latitude is not the same as one degree of longitude (except at the equator).
Analogously, in the sky, one declination degree is not the same as one right ascension degree.
I thought the situation for right ascension applied to azimuth, but it doesn't.
Both azimuth and declination are measured on "great circles" (declination is measured on a half circle, but same general idea), so degrees in azimuth should equal degrees in declination.
