It appears to be more of a sensor tilt issue than a tracking issue when it comes to the star shape. Looks to me they are elongated on the right hand side of the pic but not the left......if it was tracking I’d expected star shapes across the field to be the same

150 seconds at ISO 100 was the most promising I found.
Star shapes are becoming a problem even with off axis guiding.
Suggestions please.
