The RCC I is designed to correct Coma in fast Newtonian imaging systems. It provides a long back-focus of 91.5 mm measured from the T-2-thread, enabling the use of Off-Axis Guiders, Adaptive Optics and Filter Wheels. Autoguiding can be done easily with the RCC, an RCC Off Axis Guider and an Autoguiding Camera.

  • The RCC works from f/3.5 to f/6 – it is perfect on f/4
  • reproduction scale is 1:1 – in contrast to many other coma correctors, the RCC is no Barlow lens which rely on a magnification to make the larger back-focus to the sensor possible
  • The RCC is the only coma corrector which gives you enough back-focus for filter wheels or other accessories without changing the focal ratio

To attach the RCC directly to a camera (without an Off-Axis-Guider), we recommend the VariLock 46 T-2 Extension (# 2956946, T-2 part-no. #25V). It has got not only a graduated mm-scale, but also a marking at 36.5mm, to show you the perfect working distance for a DSLR with T-2-adapter. Each air/glass-surface of the triplet RCC optical system is coated with our Phantom Group Coating (R) for the best-possible transmission.

You can remove the stopper ring to place the RCC deeper inside of your focuser.

Technical Data – Overview

  • Focal position (perfect distance to the sensor): 91.5 mm measured from the T-2 thread / 94.5 mm from the M48 thread
  • inner connection (lens side): 2″ nosepiece with M48_i filter thread for 2″ eyepiece filters
  • outer connection (telescope side): T2 (M 42 x 0.75_a; without the stop ring M 48 x 0.65_a
  • longest overall depth: 73 mm / without the stop ring 75 mm / without the stop ring and RCC Off Axis Guider 84mm
  • Diameter of the housing: 50.8mm/2″
