PrimaLuceLab 3-inch Eyepiece Holder for ESATTO 3-inch and ARCO 3-inch

3-inch eyepiece holder for the ESATTO 3-inch and ARCO 3-inch

This PrimaLuceLab eyepiece holder accommodates a camera or accessory with a 3-inch slip-on mount on the ESATTO 3-inch and ARCO 3-inch models.

An internal brass ring distributes the clamping force across the inserted slide and minimizes any marks the screws might leave directly on its surface. The three screws, spaced 120 degrees apart, hold the accessory in place.

The part attaches to the M81 interface of the designated system. Its 12.5-mm thickness must be taken into account during installation, particularly when a camera and accessories already occupy part of the available mounting space. The manufacturer mentions heavy accessories without providing a specific load rating here; therefore, no maximum load capacity is specified for this connector.
