This adapter is mainly intended for mounting cameras at the primary focus of Takahashi Mewlon telescopes. It can also be used as a M43 male to M42 male conversion ring, if needed for other types of mechanical mounts.
The input mechanical interface has a M43 x 0.75 male thread. The output mechanical interface has a M42 x 0.75 male thread (T-thread). The standard T thread allows you to get a complete photographic train fully screwed at the focus of the Mewlon, whether it is a simple DSLR or a camera equipped with an off-axis guider or a filter wheel.
The reference surfaces, in and out, are shown on the schematic of the Characteristics section. We invite you to refer to the system-charts that are specific to your Takahashi Mewlon telescope to know what kind of assemblies is possible.
