Its my understanding that the longer the focal length of a refractor, the less chromatic aberration. Therefore, I'm wondering how Orion's 120mm / 1000mm fl performs. Their advertising literature says it is fully baffled, but what does that mean? I would think that the scope with a good diagonal (Lumicom or Televue Everbright) would have very good optical qualities. Any user comments? I'm especially interested in how it performs on planetary observation. Thanks.
