Designed to offer the best performance for astrophotography

The special design allows the ESATTO 3.5” LP to have an impressive 10kg payload capacity with the focusing smoothness that is required by modern astrophotography techniques (eg. autofocusing with V-curve).


 

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 allows you to configure your telescope by selecting OTA and mount type and by connecting to any camera, autoguider, mount, or filter wheel that is has an ASCOM driver (tested with ASCOM platform 6.4 and later). And if you install PLAY on an EAGLE computer, it automatically adds more advanced features!

Note: In order to use PLAY you have to have either the ESATTO focuser or SESTO SENSO 2 focusing motor. PLAY natively supports the new ARCO rotator and ECCO environmental module.

 


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.

 


Connection with a single cable to ARCO camera rotator and field de-rotator

ESATTO includes a special port for ARCO, the robotic camera rotator.  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.
