PrimaLuceLab ESATTO 4-inch with ARCO 3-inch

PrimaLuceLab ESATTO 4-inch with ARCO 3-inch

This PrimaLuceLab kit includes the ESATTO 4-inch eyepiece holder, the ARCO 3-inch rotator, and the adapter that connects them. It combines remote-controlled focusing and rotation in a mount with a stated thickness of 93.0 mm.

The overall clear aperture is 76.3 mm. These two measurements refer to the assembled unit; they should not be confused with the dimensions of the ARCO body alone. The necessary connections to the telescope and camera depend on your optical system.

ARCO connects to the ESATTO via a short cable, while the connection to the computer uses the ESATTO’s USB port. The package insert recommends adding a 12-volt power supply if the PC’s USB port does not provide enough power.

PLAY allows you to control both functions; ASCOM drivers provide access to Windows software compatible with ASCOM eyepiece holders and rotators. Depending on the mount and how it is used, ARCO is used for camera framing or field rotation correction. The telescope, mount, and camera are the components that need to be paired with this system.
