The Baader Rowe Coma Corrector (RCC) eliminates coma in fast Newtonian imaging systems between f/3.5 to f/6 without manipulating the focal length. The RCC has a large backfocus requirement of 91.5mm, allowing you to connect accessories such as off-axis guiders, filter wheels, rotators and more. The triplet lens design has Phantom Group wideband multi-coating on all air to glass surfaces. The coating treatment delivers the highest transmission combined with the lowest amount of scatter and reflections across a very wide spectral range. There is a removable stopper ring which allows you to place the RCC deeper inside your focuser if necessary. The 2" nosepiece is threaded for 2" mounted filters.
