Here's a shot I took last night during a Perth Observatory Volunteer viewing night. I got one guy to turn the dome during the 30s shot so the door provided a nice rolling shutter to the interior.
Camera D810A, iso6400, 30s, f3.4@14mm, tripod, processing in Nikon Capture NX-D.
I took a few more images during the night: link to the flickr album here:
