Glider daughter's dispatched deviating around star! (5)
I believe the answer is:
rigel
'star' is the definition.
(star in the constellation Orion)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for rigel that I've seen before include "Orion's brightest star" , "shiner" , "Brightest star in Orion" .)
