    Dust donuts are imaged from specks very close to your camera sensor...the mirror on the Secondary is not the culprit. Stop worrying about them. That s what

When I rotate the camera the donuts stay in the same position are these on the secondary mirror on the corrector. If so I have a real problem being that the mirror is clean, this will mean it needs recoating. Question does the mirror housing have a screw arrangement that hold it in place. I have some photos I can show what my problem is if anyone is interested.
