Hi Simon.
Maybe try testing on the stars, that might bring the focal plain closer to the scope.
Is the reducer an add on that you have put in the image train?
Are you saying that documentation says the sensor is to be 75mm from the reducer threads but you have done it at 100mm from the threads?
Where abouts do you have the reducer in relation to the OAG and filter wheel?
