Autumn skies may be less brilliant than those of other seasons, but there is plenty of interest. In this programme Patrick Moore discusses the main features, with special reference to binocular observations, and gives a timetable for the eclipse of the moon which will be seen on 17 October. And the continuing story of Halley's Comet. The latest stunning series of black and white pictures from Giotto's camera - seen for the first time on television - will give scientists the clues to exactly what organic materials the comet contains.
