| Focal Length Description | The original focal length of the telescope, before using the reducer corrector, is not explicitly mentioned in the provided information. However, it can be inferred that for an f/10 system, the reducer corrector reduces the focal length by 37% to make it an f/6.3 system. Thus, if the focal length of the f/10 system is F, then the focal length after using the reducer corrector would be 0.63F (f/6.3… |
