Telescope alignment

Hi,
Having just taken receipt of my new scope (Celestron C8-NGT Computerised) I am attempting to align it. This is my first computer controlled set and I'm a bit stuck. Having given the gps position I am attempting to do a quick align as I cannot see three stars from the list from my observing location to undertake a 3 star align. However, when I ask it to move to the moon it is ...

Tonight's Sky at Night on BBC1

Anyone here see this month's programme reporting from Mauna Kea? The range of telescopes there plus the sky conditions make my scope seem like a cheap toy & makes me feel like giving up with what we get in cloudy old Britain.

Certainly very impressive. Is it my imagination - but does Chris Lintott seem to be taking over the reigns of SAN more & more?
