There ya go. Learn somethin' every day.

For some reason, I thought the gap between Polaris and the North Celestial Pole was increasing. Nope.

The polar axis 'scope has the inner circle etched at 48 arc-minutes. It was made in the late 80s or early 90s.

I found a little table in the EQ6 documentation.

year	xxxxx	distance in arc-min
2000		45
2002		44
2004		44
2006		43
2008		43
2010		42
2012		42
2014		41
2016		40
2018		40
2020		39

So the 40' to 41' I was getting last night was in fact correct.

This made me go back and check if all that work I put into a custom Polaris reference guide plate was correct. Yes. But now I see it is out of date again! Ha ha.
