The shots on Siding Spring Observatory bring back memories.
Long before the SSS telescope was installed (which is located behind the Warrumbungle nightscape that Mike shot), there used to be the 16" telescope associated building on that hill -- which also contained an electronic workshop etc. where my Dad worked in the 1980s. The good old 16" was actually the first dome on the site, before even the 40", installed as the test-bed instrument for the site by Bart Bok. It was long decommissioned for professional use by the time I lived on the mountain, so I got to use it for my amateur jaunts (and the nearby 24" (
