PrimaLuceLab ARCO 2 Camera Rotator

The ARCO 2 is specifically designed to integrate with PrimaLuceLab's ESATTO focusers and SESTO SENSO 2/3 controllers. It requires these specific units for power and control, so it is not compatible with third-party focusers.

With a thickness of only 20mm, the ARCO 2 is designed to have a minimal impact on your back-focus requirements. However, you should always account for this 20mm distance when calculating your total imaging train length to ensure your camera reaches the sensor plane correctly.

Yes, the unit is constructed from durable aluminum and designed for rigidity. It is built to support heavy imaging equipment without flex, ensuring your camera remains stable during long-exposure sessions.

When using an alt-azimuth mount, the ARCO 2 compensates for field rotation by continuously rotating the camera to match the sky's movement. You will need to use the compatible control software to manage this process, which ensures your target remains properly oriented throughout your session.

Yes, a resolution of 1 arc second per step provides extremely fine control over your camera's orientation. This level of precision is more than adequate for framing deep-sky objects or aligning your sensor perfectly with your target.

The ARCO 2 features integrated cable management when connected to an ESATTO or SESTO SENSO unit. This setup eliminates the need for extra power or data cables running from the rotator itself, keeping your imaging train clean and reducing the risk of cable snags.
