A starry role, with moon involved? (10,5)

I believe the answer is:

astronomer royal

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

'a starry role with moon involved?' is the definition.
I can't judge whether this defines the answer.

'a starry role with moon involved?' is the wordplay.
'with' means one lot of letters go next to another.
'involved?' indicates an anagram (involved can mean confusing or complex).
'starry'+'role'+'moon'='starryrolemoon'
'starryrolemoon' anagrammed gives 'stronomerroyal'.
'a'+'stronomerroyal'='ASTRONOMER ROYAL'

Can you help me to learn more?

(Another definition for astronomer royal that I've seen is " Appointed skywatcher".)
