FS60CB flattener - eggy stars
Referring to the FS60CB system chart and use of the flattener.
Having followed the diagram and all combinations of adapters / elements shown, stars in all corners are eggy. More like long grain rice?
Thinking this through. Given that there is no way of attaching the flattener backwards, it seems that the distance between the flattener and camera rotator / focus tube and / or flattener and camera is important - though, the SD ring is optional, which leaves distance to the camera.
Worse, could the flattener elements have moved? Is that likely? I do not recall dropping the flattener and there are no rattles.
