The RMSA8 thread-to-thread adapter contains an internal RMS (0.800"-36) thread and an external M42 x 1.0 thread. Made of anodized aluminum, it is machined with both threads inline and may be positioned anywhere along a threaded tube. It is typically used to mount an RMS microscope objective to an SLR camera, in combination with an M42 x 1.0 to SLR bayonet mounting adapter.
