(1) Get yourself a notebook and pencil
(2) Sketch the basic constellation layout
(3) Jot down anything new or interesting you learn from the episode
(4) Try and answer the challenging questions I set, either by hitting "google" or looking at astronomy books.
Enjoy. Horizon/Nova it is not - but I'm aiming to pass on some basic knowledge rather than to dazzle with orchestral music, globe trotting reports and special effects!!!
