While you're here, how about checking out the Astronomy Book List ?

Hi Larry!

Sorry if any of these questions sound silly - but sometimes we all overlook
the obvious.

1. Are you *sure* Diphda/Cetus are below the horizon *at the time you are
trying this*?
2. Is your N/S switch on the control panel set to "N" ?
3. You said your time was correct - did you double check the date?

Just a few things to think about.
