PrimaLuceLab Adapter ESATTO 3" for Takahashi Telescopes with M72 Thread
This PrimaLuceLab adapter provides a secure, direct-threaded connection between the ESATTO 3" robotic focuser and Takahashi telescopes that feature an M72 thread. It lets you thread the low-profile ESATTO 3" directly onto the back of the telescope, upgrading your Takahashi optical tube with the precision of motorized focusing.
Direct M72 Threaded Connection for Takahashi Telescopes
By creating a rigid, threaded connection, this adapter ensures your entire imaging system—from the focuser to the camera and any accessories—is securely coupled to the optical tube. This eliminates potential flexure or misalignment that can occur with less robust adapters, which is critical when using heavy imaging setups. The adapter is specifically designed to allow the ESATTO 3" focuser to be used on compatible Takahashi refractors and other OTAs, unlocking robotic focusing capabilities for these premium instruments.
Locking the ESATTO 3" to the Adapter
Thread the adapter onto the M72 thread at the back of your Takahashi telescope, then install the ESATTO 3" on the adapter and lock it with the thumbscrews. To frame your camera at a precise angle, PrimaLuceLab offers ESATTO 3" camera adapters with stop ring.

What is the primary purpose of the PrimaLuceLab ESATTO 3" to M72 adapter?
This adapter is designed to securely connect a PrimaLuceLab ESATTO 3" motorized focuser to a Takahashi telescope that has an M72 threaded visual back. It allows you to upgrade your telescope for high-precision, remote-controlled focusing.
Which Takahashi telescopes are compatible with this PrimaLuceLab adapter?
This adapter is designed for Takahashi telescopes with an M72 thread on the back of the tube. Always check the specific thread specification on your telescope's rear cell or current focuser to confirm compatibility.
Will this adapter add significant back focus to my Takahashi FSQ-106ED setup?
The ESATTO 3" itself is low profile; the adapter's optical length is not published.
Can I use this adapter to attach my camera directly to my telescope?
No, this adapter is specifically designed to connect the ESATTO 3" focuser to the telescope. It is not intended for connecting a camera directly. The adapter's threads are designed to mate with the ESATTO focuser body on one side and the telescope on the other.
I want to image the Horsehead Nebula (Barnard 33) with my Takahashi telescope and ESATTO 3". How does this adapter help?
It lets you thread the ESATTO 3" directly onto your Takahashi telescope, for the precise, repeatable focusing that brings out the faint details in the nebula.
