The ESATTO 2″ LP is a motorized eyepiece holder from PrimaLuceLab designed for telescopes with limited rear space. Its 32-mm body provides a clear opening of 50.9 mm with a 10-mm focusing travel.
The low-profile design is intended for astrographs and other instruments with a short remaining backfocus. According to the manufacturer’s specifications, the eyepiece holder can support up to 5 kg. Its movement is controlled with a resolution of 0.03 µm per step. This resolution refers to the motor’s step size; it does not represent an absolute measure of focus accuracy for any given camera or telescope.
The ESATTO 2″ LP is designed to be mounted on a Celestron EdgeHD 8″ without touching the primary mirror locking knobs or the manual focus control. The manufacturer also notes that it can be used with the optional 0.7x reducer, which changes the back focus from 133 to 105 mm. This compatibility requires the appropriate mechanical interfaces.
The USB-C port connects the eyepiece holder to EAGLE or a Windows computer. PLAY enables its use in an astrophotography setup; the ASCOM driver allows control via compatible third-party software. Wi-Fi and the Virtual HandPad also allow for control via a phone or tablet. The status LEDs can be dimmed to minimize their brightness during a session. The presence of a thermal sensor port does not mean that a thermal sensor is included.
The telescope-side and camera-side adapters must be selected separately based on the interfaces and available space. The stop rings on the camera adapters are used to lock the camera’s orientation. The 32 mm measurement refers to the eyepiece holder body and does not represent the length of a fully equipped optical train. When selecting extension tubes and adapters, you must take into account the corrector, the camera, and the focus position.
The ARCO port allows you to power and control a rotator via a single dedicated connection, without a USB connection or an additional 12 V power supply directly to the ARCO. This makes it possible to adjust the framing and use field de-rotation in a compatible altazimuth configuration. The rotator and its adapter remain optional. The manufacturer specifies that a USB cable is included for connecting to a computer, but the product page does not explain why a universal connector kit or an AC power adapter is automatically included in the package.
