Product Overview
- Name / Model: Adapter from M56 → SC with Stop Ring for ESATTO 2″ (SKU PL3600225)
- Purpose: Provides an interface to connect the ESATTO 2″ focuser’s M56 male draw‐tube thread to any accessory or camera with a SC (Schmidt-Cassegrain) female thread. At the same time it incorporates a stop ring that lets you lock the rotational orientation of the mounted accessory/camera.
- Optical thickness: The adapter’s optical path length is 4 mm total (1.5 mm adapter body + 2.5 mm stop ring) according to manufacturer specs.
- Typical price: Around US $150 (varies by dealer) for this specific adapter.
Key Features & Benefits
- Thread conversion: Enables compatibility between the ESATTO 2″ focuser (M56 draw‐tube thread) and standard SC‐threaded accessories (female SC). This is particularly valuable if your telescope or accessory uses SC threads (common in many SCT/EdgeHD systems).
- Stop ring for rotational alignment: The included stop ring allows you to fix the orientation of your camera or accessory once mounted. This is especially important for astrophotography setups where sensor/camera orientation, cable exit direction, guiding ports etc. need precise alignment.
- Minimal added optical length: At only ~4 mm added path, the adapter keeps the optical chain short, helping preserve back‐focus margin (important for fast optics or limited back‐focus setups).
- Quality build & compatibility: Designed specifically for ESATTO 2″ (and compatible with the ARCO 2″ rotator interface) making mechanical integration straightforward.
