Hi Greg,

I can't say that I've tried Sirius during the day.  I guess I will
have to try that this fall when I return to the ship.
I will say that it is usually the first star I knock out when I shoot
a round.  I am wondering if Canopus can be
observed during the day as well?   I will have to look for it.

I have shot lunars using Bruce Starke's tables.  My best was a 17
second error.  I tend to like to use Planets
as the comparing bodies.  The real trouble there is that it takes me
30-40 minutes to do the reduction.  I do find
the actual taking of that sight the most challenging.

I have done a few daytime fixes.  I usually get a meridianal passage
of venus and cross it with either
a sunline or a "longitude by chronometer" sight of the sun.  If the
moon is out, I usually throw that into
the mix as well.  That is typically a early morning observation.

Well off to work on the deck.  I'm sure to be thinking of Celnav when
I'm out there.
