- It is identified as model PL3600212.

✅ Key Specifications & Features
| Feature / Spec | Detail |
|---|---|
| Thread interface (telescope side) | SC 3.3″ male/thread (fits large SCT / EdgeHD rear cell thread) |
| Thread interface (focuser side) | Compatible with ESATTO 2″ rear draw-tube interface (built into adapter) |
| Optical thickness / back‑focus impact | Adapter adds only ~2 mm of optical thickness, leaving approximately 77 mm of back‑focus available for your camera and accessories when used with ESATTO 2″. |
| Compatibility | Designed for use with large SC‑thread telescopes: e.g. Celestron SCT 11″ & 14″ and EdgeHD models 925, 1100, 1400. |
| Use case | Allows a motorized focuser (ESATTO 2″) to replace the stock SCT/EdgeHD back, enabling precision focusing and stable imaging train mounting. |
| Mounting benefits | Retains generous back‑focus even with the adapter + focuser installed — important when using focal reducers or cameras with significant back‑focus needs. |
