The ESATTO 3.5" and ARCO 3" are designed to work together, so you only need one USB cable to connect to both through the ESATTO and a short cable to connect the ESATTO to the ARCO.
With ARCO you can remotely control the rotation angle of your camera to achieve perfect framing of the object. If you have an alt-az mount, you can use ARCO to de-rotate the field without the need of an equatorial wedge. By connecting ESATTO 3,5” LP to ARCO 3” you will have a rotating focuser with just 58.5mm of thickness and 76.3mm of free aperture.

Includes PLAY, the Prima Luce AstrophotographY Software
ESATTO 3.5” LP comes with PLAY, the all-in-one and easy to use astrophotography software that allows you control your focuser and easy remote operation. ESATTO comes with a sturdy USB-C port (which you can connect to any USB type port thanks to the cable included in the box) to connect to EAGLE or any Windows computer (tested with Windows 10 computers).
PLAY also allows you to use the ARCO as both a camera rotator and field de-rotator, for use with Alt-Az mounts.

Many adapters available to connect to telescopes and cameras
ESATTO 3,5” LP draw tube travel moves on the telescope side and different optional pre-made adapters are already available to connect to different telescopes. If you don't see what you need, you can contact us for custom adapter manufacturing.
On the camera side, ESATTO 3,5” LP has a M98x1 female thread and, through a complete series of optional camera adapters with stop ring, it allows you to directly connect cameras or to the ARCO rotator. The stop ring allows you to lock the camera at a precise angle to better frame the object.
