Thanks mate @shallowseasgallery , the coffee club discussion today agrees with you !! I was using the smaller Nauticam Glass port – 140 mm (?) , however , yes I see my choice of F stop was the culprit :{

side note – great coffee catch up today – thanks to all that attended – I always get both motivation and insights .
