what an excellent first light image - looks like it will be a very good system when you get the minor alignment bugs sorted.
might possibly be a bit of image plane tilt - focuser maybe? First thing to do though is collimate - it is a bit out and you will not be able to assess any other possible alignment problems until you do that.
