Do my stars look too big in this ?

Hey guys.
Just a quick simple question, with a probably very complex answer
But... Do i my stars look big in this ?
This is as small as i could focus them, but they still look rather comical in size, is this just an artifact that is easily removed post ? or is my collimation WAY out or something ? (I do collimate before eqach imagining session, but i only own and know how to use a laser collimator).

I tried to think of a nice big bright, and therefore easy, target to shoot my first deek sky shot on, so i though. M42..... what else. Now i have discovered it is one of the more difficult objects to photograph.

Anyway this photograph is of m42 6second exposure at f5 through the red channel with a DSI pro. Guided.

Thanks for the help.
