Collimation issue? egg stars?

I seem to have issues with egg shaped stars in the upper right and upper left corners of my images.
I am using a SkyRover 115 triplet with the recommended flattener and an ASi294MC Pro camera.
Could my focuser be out of collimation with the front lens?
Any thoughts about the cause and cure would be gratefully appreciated!
