Giant group of stars (5)

I believe the answer is:

orion

I believe this is a double definition.

'giant' is the first definition.
(thesaurus)

'group of stars' is the second definition.
(I know that Orion is a constellation)

(Other definitions for orion that I've seen before include "Group of stars" , "Hunter slain by Artemis" , "Large constellation" , "Constellation on the celestial equator -- giant hunter of Greek mythology" , "His belt is in the heavens" .)

I've seen this clue in The Telegraph and The Globe and Mail.
