few options:
you can download Stellarium or similar software for free and find objects
that way -
http://www.stellarium.org/
download a free star map -
http://www.skymaps.com/
more expensive option is to install a GoTo system on your scope and this will more or less take you to the object your looking for
all of this also depends on what your scope and what you will be able to see through it
hope that gives you a start though ..
