Darryl, in my experience, using a laser to point your scope is the easiest way - no bending the head to look through finderscope or 1x red dot style finders. If you are good at looking at a star chart then looking up at the sky and being able to see exactly where you need to point the scope, it will be very easy for you to use the laser. Just set up so the "end" of the laser beam is visible inside the FOV of a suitable eyepiece - probably in the 25-40mm fl range. My laser is a nice narrow green line with a clear "end" in my 30mm eyepiece.

So I'm forever doing somethng like - OK, I need to be 40% of the way from that bright star to that other bright star, and then a little bit above. Put laser in place, turn laser on, move scope until the end of the laser is there, look in the eyepiece and there it is!

Now, if people are imaging around you, expect something to come flying out of the dark at you, if you are painting the sky with your laser (ouch! )! Also, it can draw attention to yourself, if you are trying to hid away behind trees or a building in some public place at night! I believe that someone tens of metres away can still see the beam.
