my standard check with this is pull the camera out, put a eye piece in and look at the star itself. go in and out of focus, if the star doesn't come in though focus and out the other side as a circle. then you have issues.

Make sure the primary isn't twisted because funny things happen.

It does look like a little bit of coma though to be honest.

Thanks Adam for your look in and Brendan, I will slot the eyepiece in and do a star test...when the skies clear up and see how that looks.
