Manage after ordering steel spyglass (9)
I believe the answer is:
telescope
'spyglass' is the definition.
(thesaurus)
'manage after ordering steel' is the wordplay.
'manage' becomes 'cope' (manage can mean to cope or do well).
'after' is a charade indicator (letters next to each other).
'ordering' indicates an anagram.
'steel' is an anagram of 'teles'.
'cope' after 'teles' is 'TELESCOPE'.
(Other definitions for telescope that I've seen before include "Compress like optical instrument that magnifies" , "Glass" , "It magnifies the image of distant objects" , "Astronomer's instrument" , "View distant objects through it" .)
