C. Takahashi Mewlon 250 Secondary
We don't offer knobs for the Mewlon 250 secondary because there isn't enough room around the electric focuser to fit knobs of a useful size. Furthermore, the factory push-pull screws are so close to each other that the replacement knobs would need to be staggered in height, adding to the inconvenience.
