With coma corrector, 2 original distinct dust donuts on right hand side of field about half out
Without coma corrector 2 faint dust donuts on left hand side of field about quarter of the way out , original 2 distinct dust donuts have disappeared
So I’m assuming their not the same dust donuts due to position and rotation plane from centre
So my question is why have the original 2 disappeared ? coma corrector May have had dust or scratches
But why now 2 new faint ones appear that were on the original
Doesn’t make logical sense ??
