PrimaLuceLab Adapter from M56 to M57 with Stop Ring for ESATTO 2″ / ARCO 2″ — the M56 → M57 adapter designed for use with PrimaLuceLab ESATTO 2" Robotic Focuser (and optionally PrimaLuceLab ARCO 2" Rotator) — tailored for astrophotography setups.
Product Overview
- Name / Model: Adapter from M56 to M57 with Stop Ring (for ESATTO 2″ / ARCO 2″) — Reference/SKU: PL3600227.
- Purpose: Allows you to connect any camera or accessory with a female M57 × 0.75 thread to the M56 male draw‑tube thread on ESATTO 2″ (or the M56 output of ARCO 2″).
- Why it matters: Many aftermarket astrophotography accessories (nosepieces, reducers, visual backs, visual accessories) may use M57 — this adapter makes ESATTO + ARCO compatible with those items, extending the versatility of your imaging train.
Key Features & Specifications
- Thread conversion: M56 male → M57 × 0.75 female connector — enabling mounting of M57‑threaded cameras or accessories on ESATTO 2″ / ARCO 2″.
- Stop‑ring included: Built-in stop‑ring lets you fix the rotational orientation of the attached camera or accessory. Useful for precise framing, controlling sensor orientation, cable routing, or aligning finders / OAGs / filter wheels.
- Optical path length impact: Adds approximately 4 mm to the optical path (≈ 1.5 mm adapter body + 2.5 mm stop‑ring).
- Compatibility: Works with ESATTO 2″ draw‑tube output or ARCO 2″ output (which shares the same M56 male threading), so you can use it whether you have only the focuser, or a focuser + rotator stack.
- Build / Construction: Standard from manufacturer (aluminum, anodized or machined metal) — intended to maintain structural integrity and alignment for imaging trains that may include cameras, reducers, filter wheels, etc.
