The dark tower even gets a look in at the top to the right of centre.
Melbourne had a sort of clear night but with the Moon only NB was useful.
I used Logmein to control the laptops in the observatory from inside where it was nice and warm. Logmein works over the internet so when I get a robotic mount I can collect data from anywhere. There is a free version that works very well.
