Hi Allan, that's not what I meant. I don't image with any filter on the nose piece anymore and the reflections I'm talking about (donut shaped) are still present (Alnitak, M45 to name a few). See my shots and Duncan's of the pleiades.
The Hyperstar has a lot more glass surfaces than the MPCC and the camera is very close to it too and I don't get those reflections.
