Bob,just a thought
is there anything up around Perth Observatory,or is it to woody?
I suppose it may be difficult to find an open space large enough
I was up there a couple of years ago and it wasn't to bad ,being so close to Perth.
In another post I said that GINGIN wasn't to good
but I suppose I was comparing it to my DARK SKY here in Queensland
.
I hope you can find somewhere,so that you can enjoy more of your hobby
