AAVSO Variable Star Atlas

Hello,

I am thinking to get the AAVSO Variable Star Atlas to
use for both variable star observing, and as a general
deep-sky atlas. Some reviews I found on the Net say it
is OK for both purposes, but I'd like to get input from
someone who is using it first hand.

Is it good enough for regular deep-sky observing -
nebulae, galaxies? When it comes to observing variable
stars, are the charts detailed enough not only to be
used to find the star in question, but also to allow
reasonable magnitude estimation - do they generally have
enough comparison stars with plotted magnitude around?
Any other comments?

Thanks,

- Alex
