Wanderer Astro Bolted Adapters for FETA M92
This series of four bolted adapters provides robust, system-specific connection options for the Wanderer FETA M92 focuser and tilt adjuster. Options include M68x1 and M72x1 female thread converters that establish a 20 mm back focus path when used in pairs, and direct-mount adapters for Moravian C3/C4 and C5 imaging systems. Each adapter fastens securely to the FETA M92 with the included M3 screws, ensuring a rigid and reliable optical train.
M68 & M72 Adapters: 20mm Back Focus Conversion
The M68x1 (WA-WFETA92-M68FA) and M72x1 (WA-WFETA92-M72FA) adapters convert either side of the FETA M92 to a standard female thread. While a single adapter can be used, installing two adapters, one on each side, creates a female-to-female connection with a total effective back focus of 20 mm. Slots on the adapter allow 360-degree rotation, so you can set the desired rotational position before tightening the screws.
-
M68x1 Adapter: Gives either side of the FETA M92 an M68x1 female thread.
-
M72x1 Adapter: Typically suitable for the Takahashi TOA-130 and TOA-150, which have M72 threads.
Moravian C3/C4 Adapter for M68 Systems
The WA-WFETA92-MRC3A adapter bolts the FETA M92 directly to the Moravian M68 adapter used on C3, C4, G3 and G4 cameras, filter wheels and the M68 OAG MKII. This creates a solid, non-threaded connection by using the five M3 screw holes on the front of the Moravian M68 adapter.
To install, you first secure the adapter to the camera side of the FETA M92 with the silver M3 screws. After removing the original screws on the Moravian adapter, you then use the longer black M3 screws to attach the Moravian hardware, passing the screws through the adapter from the telescope side of the FETA M92. Note that this adapter is not compatible with the Moravian M68 OAG MKIII.
Moravian C5 Adapter for M85 Systems
Designed for Moravian C5 systems, the WA-WFETA92-MRC5A is a two-part adapter system that bolts the FETA M92 to Moravian M85 accessories. It is compatible with Moravian M85 adapters that feature either 7 or 8 M3 screw holes, accommodating the C5 camera, filter wheel, and M85 OAG.
Installation involves three steps. First, attach Adapter 1 to the camera side of the FETA M92 with silver M3 screws. Second, attach Adapter 2 to your Moravian M85 adapter using another set of silver M3 screws. Finally, bolt Adapter 1 and Adapter 2 together using the longer black M3 screws, inserted from the telescope side of the FETA M92.
Choosing Your FETA M92 Adapter: A Version Guide
Selecting the correct adapter depends entirely on the hardware you intend to connect to your FETA M92. Each version is purpose-built for a specific interface and is not interchangeable.
-
For general M68x1 components: Choose the WA-WFETA92-M68FA. Purchase two if you need M68 female threads on both sides of the FETA M92.
-
For Takahashi TOA-130/150: Choose the WA-WFETA92-M72FA to match the telescope's M72 threads.
-
For Moravian C3/C4 cameras with M68 OAG MKII: Choose the WA-WFETA92-MRC3A for a direct bolted connection.
-
For Moravian C5 cameras with M85 OAG: Choose the WA-WFETA92-MRC5A two-part adapter system.

Which Wanderer adapter do I need for a Takahashi TOA-150 and the FETA M92?
You should select the M72 Female Adapter (WA-WFETA92-M72FA). This adapter converts either side of the FETA M92 to an M72x1 female thread, which is typically suitable for the Takahashi TOA-130 and TOA-150 with their M72 threads.
How do I get M68 female threads on both sides of my Wanderer FETA M92?
To achieve M68x1 female threads on both sides, you must purchase two of the M68 Female Adapters (WA-WFETA92-M68FA). When one is installed on each side of the FETA M92, the total effective back focus of the assembly will be 20 mm.
Is the Wanderer Moravian C3/C4 adapter compatible with the M68 OAG MKIII?
No, it is not. The Moravian C3/C4 Adapter (WA-WFETA92-MRC3A) fits Moravian M68 adapters with five M3 screw holes on the front, including the M68 OAG MKII. The MKIII has no usable screw holes for mounting; for it, use the Bolted M68 Female Adapter connected to the OAG with an M68 male to male adapter.
What is the purpose of the two-part design for the Moravian C5 adapter for the FETA M92?
The Moravian C5 Adapter (WA-WFETA92-MRC5A) uses a two-part system to create a secure, bolted bridge between the FETA M92 and the Moravian C5's M85 adapter. Adapter 1 mounts to the FETA, Adapter 2 mounts to the Moravian hardware, and then the two adapters are bolted together.
Can I rotate my camera after installing the M68 or M72 adapter on the FETA M92?
Yes. Both the M68 and M72 adapters feature slotted mounting holes. This allows you to rotate the adapter a full 360 degrees to set the desired rotational position before you fully tighten the M3 screws to lock it in place.
