Such a pity that they gave him so little air time and resources for his
program ("The Sky at Night" was it?) - he could have easily filled an hour slot and still kept us captivated - imagine what he could have done today with the ready affordability of telescopes in getting young people into it.
The rush to get as much as possible into the short time slot did exaggerate any eccentricity he had but in a way it conveyed the enormity of the field of astronomy and defined one's impression of his character that is unforgettable.
Interesting that he died close to the time of the first man on the moon - while Princess Di's passing was perhaps eclipsed by coinciding with the passing of Mother Theresa, I don't think I'll remember this time any more for Neil Armstrong than for Patrick Moore, he is right up there too.
