PrimaLuceLab 2" Visual Back for ESATTO 2" / ARCO 2" — the 2‑inch visual back adapter designed for use with the PrimaLuceLab ESATTO 2″ focuser (and by extension with the ARCO 2″ rotator when used in the same imaging stack).
- Purpose: A 2″ visual‑back adapter that lets you attach standard 2″ nose‑piece eyepieces, 2″ diagonals, or cameras/accessories with a 2″ barrel directly to an ESATTO 2″ focuser (or ESATTO 2″ + ARCO 2″ rotator) — converting the M56 thread of the focuser draw tube into a 2″ barrel interface.
- Use‑cases: Visual observing with eyepieces (through diagonal or directly), or astrophotography / prime‑focus imaging with a 2″–barrel camera nosepiece or accessory.

PrimaLuceLab “2″ Visual Back for ESATTO 2″ / ARCO 2″ — Reference PL8410001 |
| Optical Interface |
2″ barrel (for eyepieces/2″ accessories) on camera/eyepiece side; M56 male thread on the focuser side to match ESATTO 2″ draw tube. |
| Optical Length / Path Added |
12.5 mm optical back‑focus extension added by the visual back. |
| Mounting / Lock Mechanism |
Internal brass compression ring to protect the inserted nosepiece; three locking screws (120° apart) for secure, stable mechanical connection — suitable even for heavy cameras or accessories / diagonals. |
| Compatibility |
Works with ESATTO 2″ focuser draw tube. Because ESATTO can interface with ARCO 2″ via its dedicated port, this visual back can also be used in a focuser + rotator stack (provided thread interfaces line up). |
| Use‑case Flexibility |
Useful both for visual astronomy (eyepieces/diagonals) and astrophotography (2″ nosepiece cameras or accessories). |
