I happened to randomly watch this month's Sky at Night earlier this week. I catch it maybe few times a year. I remember thinking at the time that it was remarkable how the dude kept going, despite clearly being unwell. I'm not really particularly into astronomy, and certainly not the practical side, though find it interesting as a general topic. But his enthusiasm for the subject was always quite remarkable, and infectious. A national institution if there ever was one. RIP Sir Patrick.
