This is a fine idea and one that everyone should follow. I make it a
point check my charts beforehand to memorize stars within my field of
view for magnitude estimates. If one plots you can also highlight in
some manner these stars and refer to them during your observing session.
It is nice to have a prominent constellation such as Cygnus for this
purpose. Another useful area is Aries and Triangulum where Hamal is
+2.0, and the two stars forming the base of the triangle are exactly
+3.0 and +4.0.
