I might have to look at that, the Celestron reducer is fine for visual use and I used it a lot for that, but for AP the coatings are just not up to the task, big reflections and light loops from any bright stars in or near the FOV.
I have seen images by other people showing the same thing using that reducer so I assume it is endemic to them.
