Starting on Monday 6th February, the Planetary Society is offering a free online astronomy course over a 13 week period. The course is being given by Bruce Betts, Director of Projects for the Planetary Society.
A full syllabus and details of the course are available on the Planetary Society's website here.
The course promises to be an excellent introduction to many themes in astronomy, and is being broadcast on many cable TV channels in the USA. You can catch the programmes on the internet.
I've not seen any of the course material, but Bruce Betts makes a regular weekly appearance on Planetary Radio, and you could certainly say his segment, "What's Up", is entertaining.
So if you've missed out on Robin's local Astronomy course, this might be worth a look.
