OOPs NEPO , sorry to be the bearer of bad news , but Mak's dont usually suffer from CA , so it sounds like a collumation issue , what brand is it ,as some are easily colluminated , and some are not .
also what eyepieces and diagonal are you using , if its a prisim type it may be out of whack , and what you are seeing might be in them? .
Hope so mate , let us know .
