#19748 - Aquila-88 High-Torque Camera Field Rotator


In Stock: 1

Optec's new Aquila 88 camera field rotator replaces the venerable Pyxis 3” rotator. With a full 88mm clear aperture and less than 35mm thick, the Aquila 88 will takes its place as the next generation rotator.

Optec’s Best-in-Class ASCOM and Alpaca drivers are capable of alt-az de-rotation, image orientation and composition in addition to the traditional guide-star acquisition capability.

A new high-torque U.S. made stepper motor and new bearing system helps Optec reduce costs and pass the savings along to you.
