lodestar

I'm a little stuck... Click here to teach me more about this clue!

'celestial guide' is the definition.
(star used for navigation)

'led so astray with sailor' is the wordplay.
'astray' indicates an anagram.
'with' says to put letters next to each other.
'sailor' becomes 'tar' (slang term for a sailor).
'led'+'so'='ledso'
'ledso' is an anagram of 'lodes'.
'lodes'+'tar'='LODESTAR'

'following' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.

Can you help me to learn more?
