m42 questions newtonian first light

I shot this when the seeing conditions were less than ideal. There was high level cloud which obscured the running man nebula and I was unable to rectify this - using my limited processing skills. Also the stars are egg shaped on the periphery I am not sure whether this is a coma corrector issue or the winds that were buffeting my 200mm f5 newtonian. What has caused the double spikes on the bright star to the left of m42? Camera used was modded sony A7r mirrorless. About 3h of 120s subs. (Added image showing running man a bit better).
