All show, no go! The idea is OK, but it is massively overpriced - over two thousand Euro for a 7 Kg all-in small refractor and mount. I think the more technically minded astrophotography experts on this very forum could demonstrate a similar system for much less. Might be OK for the iPhone generation though.

More of general science than astronomy, but Nature (the science journal) do regular podcasts.
