Wow how cool is that I want one, but it seems that they can only look to the Heavens in one direction.
Depending which way it is facing I suppose, the Stars might just move overhead.
The opening faces west and backs onto a golf course. I did some work on the house next door when this was being built and was told that an amateur astronomer owned it, but can't confirm it. Nice looking place, didn't really look like something an amateur could use for practical observing, more for a casual stargaze.
