The ESATTO 2" → SkyWatcher / Orion Newton 200 f/4 and f/5 adapter (PrimaLuceLab, SKU: PL3600229 ) replaces the factory focuser on 8-inch reflectors, allowing for the mounting of a precise, remote-controlled ESATTO 2" . The aluminum collar, with an optical thickness of just 3.5 mm, screws into the original holes, maintaining the full back-focus budget and axial alignment of the optical path.

The most important features of the adapter

• optical thickness 3.5 mm – no focus shift
• mounting holes consistent with the factory exhaust system – installation without drilling
• Push-pull screws for precise adjustment of the orthogonality of the extraction
• full internal diameter 50.9 mm – no vignetting on APS-C matrices
• CNC milled 6061-T6 aluminum, hard anodized – lightweight and corrosion resistant
