- Model / Reference: PL3600237
- Purpose: Allows you to replace the stock focuser on a SkyWatcher/Orion 250 mm f/4 or f/5 Newtonian telescope with the motorized ESATTO 2″ robotic focuser.
- Design philosophy: Maintains the same focuser thickness as the original stock focuser (excluding any additional camera adapter or visual back), so you can reach prime focus without extensive modifications.
- Mounting: The adapter uses the same screw‑hole pattern as the original focuser — no new drilling or modification of the telescope tube is required.
- Alignment adjustment: It includes screws to adjust the orthogonality of the focuser relative to the telescope’s optical axis, helping ensure proper alignment when mounting ESATTO.
Key Features & Benefits
- Retains original back‑focus geometry: Because the adapter is engineered to match the thickness of the original focuser, the optical path is unchanged — facilitating prime‑focus astrophotography without complicated compensations.
- No permanent telescope modification: Uses existing screw holes on the optical tube, so installation is reversible and does not require drilling or structural changes.
- Compatibility with motorized focuser benefits: Once installed, you get all the advantages of ESATTO 2″ — smooth Crayford‑style motorized focusing, 50.9 mm free aperture, 15 mm draw tube travel, and up to 5 kg payload capacity.
- Orthogonality adjustment: Alignment screws allow fine‑tuning of the focuser’s perpendicularity to the optical axis — important for proper light path and minimal tilt when imaging.
- Easy upgrade path: For a typical 250 mm f/4 or f/5 Newtonian owner, this adapter offers a clean way to upgrade from a manual focuser to a motorized astrophotography‑ready setup with minimal hassle.
