Paracorr, Televue

People,

This question might be unecessary, but I have been wondering if a Paracorr could improve a SCT's edge performance. They are supposed to be corrected anyway, but could a Paracorr give a final touch?

Laurence,

True, the Paracorr is definitely not designed to deal with a convex secondary mirror. But when you think about it, most coma problems are at the edge of a concave mirror, which a Parcorr deals with. But a SCT has both.
