I'm glad you are keeping those Canadian computer gurus in line! ;>  Feedback
is always very important - as many of the rest of us rely on these published

I was, of course, recommending the <2002> Handbook, the one with the
correction! ;>

Gee... I just checked email and the following was posted to the RASC list...
we must have an eavesdropper! ;>

In spite of these comments... the Handbook is pretty good - and is used
around the world by many observers, both amateur and professional.  When
Geoff Wolfe talked about magnitudes for the southern sky, I thought about
the bright star list as a means of getting some of the mags for the south
circumpolar stars.

Our (free) NAMN maps are still the easiest route though, for meteor
observers north of Australia! ;>
