Oh, OK that explains it. That's why the stars are elongated in the corners. The flattener will give you round stars right to the edges of your sensor and is definitely worth adding to the imaging train. It must be 63mm from the sensor. With your camera, the sensor is 17.5mm from the front edge of the camera body. The flattener comes with an adapter that is 8mm width. You will then need 37.5mm of spacers (which you already have) to get perfect stars all the way to the edges of the image. All you need to do is screw the flattener on the telescope side of your spacers and you will be set.
