Hi Tennelle, It doesn't matter where you go that is within the Perth area,
you will suffer from light pollution, but there is one thing that you can do
to improve your observing. Pick a portion of the sky for your evening's
observing, say the southern sky, for instance; go to the southern limit
of the Perth built up area, and then the worst of the pollution will be behind you. You can do the same for any direction of observing, although
I realise that to the northern edge is a long trip from Hilton.
When you are observing across the suburbs rather than the city, you will see that the pollution decreases significantly late at night when
many house lights are turned off.
Having said all that, there are a couple of things you can do that
can help. Site your scope so that as little extraneous light as possible
is visible[ street lights, neighbour's house lights, your own house lights].
A light pollution filter can be helpful too. Importantly, wait in the dark for
at least 15 minutes before you start observing, to allow your eyes to
begin to become dark adapted, and stay away from white light during
your session; even brief exposure destroys dark adaptation.
I hope this helped; happy viewing
raymo
