Hello, the US Nautical Almanac lists 173 "navigational stars", of
which a shorter list of 57 is sometimes extracted.

Actually, the table that you found in the back of the Nautical Almanac
is NOT a table of the 173 "navigational stars".
So what's with all the other stars listed in a table in the back of the
almanac called "Stars" (note that the title of the table is NOT
"Navigational Stars")?

What is listed in the Stars table is all the stars down to a magnitude
of 3.0 (and a few that are even dimmer).

Many thanks Ron!

I got a list of the 173 brightest from:

http://www.atlasoftheuniverse.com/stars.html:

They are mostly under common names, but at least some of those that
aren't,
have got common names, e.g. Theta Aurigae is Bogardus, and Upsilon
Carinae
is Vathorz Prior.

From what you say, a few of the above don't make it to the Nautical
Almanac list,
and a few that aren't above do!

Looking forward to delivery of my copy of the NA from Amazon :-)
