Omegon Step-Down Ring 109 mm to 78 mm (Adapter Ring)

Omegon Step-by-Step Ring - Connect your telescope without the hassle
With the Omegon Step Ring, you easily connect Newtonian telescopes with a 109 mm ring clamp to focusers with a 78 mm ring clamp. No improvisation, no loose adapters - just plug and focus instantly.

Stable and reliable
The adapter consists of two parts that fit together perfectly. Part A fits into the 109 mm flange of your telescope, while Part B securely attaches the 78 mm focuser. Everything stays firmly in place, even with heavy eyepieces or cameras. This keeps your image clear and stable, without wobbling or shifting.

Easy to assemble
You don't need any tools, just the included set screws. Screw Part A to the telescope base, connect Part B to the focuser, and tighten them together via the M85 thread. Within minutes, everything is ready to use.
