Baader RT-Adapter Diamond Steeltrack for Refractors - M93x1(M)

You must confirm the thread on the rear of your telescope's optical tube. This adapter features a male M93x1 thread, meaning it is designed to connect to a refractor that has a corresponding female (inner) M93x1 thread. If your telescope matches this specification, this adapter will allow you to mount a Baader Diamond Steeltrack focuser.

This depends entirely on your telescope's rear thread. You must measure or confirm from the manufacturer that your optical tube has an internal (female) M93x1 thread. If it does, this adapter is the correct component to begin your focuser upgrade for high-resolution planetary imaging.

No, this adapter is designed to prevent flexure. It creates a solid, threaded connection between the telescope tube and the Diamond Steeltrack focuser, providing a rigid foundation essential for long-exposure astrophotography of deep-sky targets like the Orion Nebula (M42).

Its sole purpose is to allow owners of refractors with a specific M93x1 female (inner) rear thread to upgrade their standard focuser to a high-precision Baader Diamond Steeltrack focuser. This upgrade typically improves focusing accuracy, stability, and load-bearing capacity for accessories and cameras.

This adapter is engineered specifically for the mounting pattern and mechanical interface of the Baader Diamond Steeltrack series. It is not designed or guaranteed to be compatible with focusers from other manufacturers.

Installation is straightforward. Remove your telescope's original focuser, thread the adapter's male M93x1 thread into the tube's M93x1 inner thread, then clamp the BDS-RT focuser into the adapter's S88 dovetail. Always ensure threads are clean and not cross-threaded during installation.
