Looking awesome Mike, and that is a serious driveway!
Have fun building your obs, I'm sure you will soon be happily imaging from your new site.
It's interesting to compare limiting magnitudes. I can just glimpse magnitude 5.6 stars near the zenith from where I am (15km from Auckland CDB), so if you can see that in the glow from Canberra then I guess your overall limiting magnitude must be 6 or deeper?
