Astral hunter (5)
I believe the answer is:
orion
'astral hunter' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for orion that I've seen before include "Constellation named for great Greek hunter" , "Great hunter of Greek myth, and a constellation" , "Star" , "Heavenly figure" , "Rigel constellation" .)
