I was just thinking Peter, it must be intriguing, maybe comforting or just plain annoying for your wife, who I assume is at home when you are away, to hear your observatory whir into action and start moving around? I can just see her out at the cloths line one evening, suddenly the still night air is broken, buuuuz, whiiir, click.."ah, there's Peter again with his obsession..." at least she knows when you have landed, careful she can track your movements better now

. Has she had to do any night assisting for you yet, or been on stand by?
