January provides the perfect opportunity to observe stars, planets and galaxies.
Sir Patrick Moore takes us on a tour of the winter sky, looking at twinkling 'variable stars' with Dr John Mason, and at planets and galaxies with Pete Lawrence and Paul Abel.
Sir Patrick and Dr Chris Lintott also point out the best objects to observe if you've had a telescope for Christmas.
