PrimaLuceLab ESATTO Adapter

This adapter is designed for Takahashi telescopes that utilize an M72 threaded interface on the rear of the optical tube. Please verify your specific telescope model's rear cell thread size before purchasing.

The adapter has an optical thickness of 26.5 mm. You should factor this into your total back-focus calculations to ensure your imaging train reaches the correct focal plane.

This adapter is specifically engineered to mount the ESATTO robotic focuser to Takahashi systems. While the thread side is standard, the focuser-side connection is proprietary to the ESATTO line.

No, the adapter is machined to provide a rigid, secure connection. By threading directly to the rear of the telescope, it maintains the integrity of your optical train better than slip-fit or compression-ring alternatives.

If you are looking to upgrade to a robotic, automated focuser like the ESATTO, this adapter is essential for a secure, threaded attachment. It replaces the standard visual back or existing focuser connection to provide the stability required for long-exposure astrophotography.
