This bundle includes the ESATTO 4" focuser, the ARCO 3" rotator, and the adapter to connect them, allowing you to take remote control of focusing and rotation in a compact focuser with just 93.0mm of thickness and 76.3mm of free aperture.

Since ESATTO focuser and ARCO rotator are designed to work together, you don't need to have different USB and power cables to connect both devices to your control computer. You will have just one USB cable to the ESATTO (and you will have to add 12V power only if your computer is not able to provide enough current through the USB port) and a short cable to connect ESATTO to ARCO.

Control focus and rotation with PLAY - Prima Luce AstrophotographY software

ESATTO focuser and ARCO rotator are provided with ASCOM drivers (so you can control them with any astrophotography softwares for Windows that supports ASCOM focusers and rotators) but they can also be controlled with PLAY, the astrophotography software just developed by PrimaLuceLab to allow easier use of telescopes with all its devices together with the cameras, optical tubes, mounts and other accessories that the user is free to choose.
