Baader Planetarium Rowe Coma Corrector for Newtonian Telescopes

Baader Planetarium Rowe Coma Corrector for Newtonian Telescopes

• Long Back Focus: The RCC-I triplet optical design has been optimized to work at a large 91.5 mm back-focus distance, enabling the use of Off-Axis Guiders, Adaptive Optics, and Filter Wheels. The RCC even allows users of DSLRs to incorporate off-axis guiding with the Baader RCC Off-Axis Guider
• No magnification increase: Unlike most other coma correctors, the RCC-I does not impart a Barlow effect - it works at 1:1, with no loss in imaging speed or reduction in field size
• Fast Imaging Speeds: The RCC-I has been optimized for Newtonians with focal ratios from f/3.5 to f/6 (nominally designed for f/4)
• Ease of Focus: Addition of the RCC-I into the optical train extends the focal point slightly (approximately 5 mm, in an f/4 system). This important attribute ensures that your system will be able to reach focus without needing to shift the primary mirror or increase the size of the secondary mirror

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.
