I believe the answer is:

radio telescope

I'm a little stuck... Click here to teach me more about this clue!

'instrument getting stellar reception' is the definition.
I can't tell whether this definition defines the answer.

'incorrectly depreciate solo' is the wordplay.
'incorrectly' is an anagram indicator (I've seen this in other clues).
'depreciate'+'solo'='depreciatesolo'
'depreciatesolo' anagrammed gives 'RADIO TELESCOPE'.

Can you help me to learn more?

(Other definitions for radio telescope that I've seen before include "Astronomical instrument" , "scientific equipment" .)

I've seen this clue in The Telegraph.
