RCC OAG off-axis guider

140° rotatable off-axis guider (OAG) for connecting to a T2 thread. This OAG was specially developed for the RCC I Newtonian coma corrector. By using this OAG and a Baader T-ring, you can use any DSLR camera off-axis, without needing additional rings or extenders, by using a crosshair eyepiece or with the help of the LVI Smartguider. The ideal chip distance then results automatically from the optical length of the T ring and the RCC OAG.
