All, ie, go off to an Italian astronomer (7)

Ross

I believe the answer is:

galileo

'an italian astronomer' is the definition.
(I've seen this before)

'all ie go off' is the wordplay.
'off' is an anagram indicator.
'all'+'ie'+'go'='alliego'
'alliego' with letters rearranged gives 'GALILEO'.

'to' acts as a link.

(Other definitions for galileo that I've seen before include "victim of Inquisition" , "US unmanned space-craft launched in 1989 to investigate Jupiter" , "Great Italian astronomer and physicist of 17th century, suppressed by Church" , "Italian astronomer and mathematician, d. 1642" , "Great Italian astronomer, a founder of modern science" .)

I've seen this clue in the Sydney Morning Herald.
