Focuser draw tube with M81 x 0.75 thread and stop ring for a perfect camera connection

To avoid any camera tilt or optical train flexure, ESATTO 3" has a M81 x 0.75 male thread where you can screw on an adapter for your camera or accessory. The optional 2" visual back is generally only used for visual observations. The stop ring allows to lock the camera at a precise angle to better frame the object.

Connection with a single cable to ARCO

ESATTO includes a special port for ARCO, the robotic camera rotator.  With ARCO you can remotely control the rotation angle of your camera to achieve perfect framing of the object. ESATTO and ARCO are designed to work together as you will only need one short connector between the two!
