An easy magnitude scale for the sumer is right overhead. I use it all the
time
and since I don't plot meteors other than full magnitudes, the following is a
good representation for the beginner/novice.
Start w/ Vega (Lyra) is mag. 0 (zero), Deneb is +1, the center of the Cygnus
cross asterism is +2, and Albiero is +3. Dimmer than Albireo is +4 and that
is
usually enough for my area with a LM average around 5.5 to 5.9 I usually
don't
see any +5 meteors (unless they are right in front of me). At the other end
of
the scale - Jupiter is hovering at about a -2.5 . So a meteor dimmer than
Jupiter but brighter than Vega must be a -1.

These are my favorite comparison star groupings for magnitudes. There is also
a 5th magnitude star within the head of Draco that I get a "feel" for. Thanks
for pointing them out Kevin.
