The Baader RCC-I (Rowe Coma Corrector) is a novel Coma Corrector by Dave Rowe with a triplet lens design optimized for f/4 Newtonian telescopes, but will deliver impressive results when used with focal ratios f/3.5 to f/6. The RCC-I has a longer than usual chip distance of 91.5 mm from the T2 thread. The long focus distance is perfect for larger setups such as a filter-wheel with Off-Axis-Guider or Adaptive Optics.
