PrimaLuceLab ARCO 2" Motorized Camera Rotator (Ref. PLLARCO2)

 Description:

The PrimaLuceLab ARCO 2" is a high-precision motorized rotator and field de-rotator, engineered to work in perfect harmony with ESATTO and SESTO SENSO 2 systems. With a resolution of 1 arcsecond per step, it enables accurate camera rotation while maintaining mechanical stability, even under heavy loads.

Its compact 20 mm profile and 50.9 mm clear aperture allow efficient integration without protruding parts that could interfere with the telescope or accessories. On equatorial mounts, ARCO 2" handles camera rotation automatically. On alt-azimuth mounts, it compensates for field rotation, allowing long exposure astrophotography with sharp results.

ARCO connects directly to ESATTO or SESTO SENSO 2 using a proprietary short cable—no USB or 12V external power is needed. It supports PLAY astrophotography software and ASCOM drivers, ensuring broad compatibility with control setups via Windows, EAGLE or mobile devices.

Additional information:
ARCO 2" is not a standalone device. It must be paired with an ESATTO focuser or a SESTO SENSO 2 motor to operate. Multiple M56 adapters are available to connect to a wide variety of imaging accessories. Full remote control is possible via Wi-Fi or USB using PrimaLuceLab's systems or software.

Easy to use with ESATTO.

You can connect ARCO 2" to all the ESATTO focusers with the proper optional adapters and control it with the ARCO cable that comes in the box. Use the PL3600412 adapter to connect ARCO 2” to ESATTO 2". Use the PL3600416 adapter to connect ARCO 2” to ESATTO 3” Use the PL3600423 adapter to connect ARCO 2” to ESATTO 4”.

Easy to use with SESTO SENSO 2.

If you use a SESTO SENSO 2 connected to your telescope’s focuser, you can connect the ARCO 2” rotator by using the optional PL3600413 2" nosepiece for ARCO 2” if your focuser has a standard 2” visual back or the PL3600424 M48x0.75 female adapter for ARCO 2” if you have an M48 male thread (for example if you have a corrector/reducer already inserted in your focuser). Like with the ESATTO, you will connect ARCO to SESTO SENSO 2 with the provided cable.

Compatible with all the M56 adapters.

Since ARCO 2” has the same M56x1 male thread found on the camera side of the ESATTO 2” draw tube, you can use any of the optional M56 adapters with stop ring in order to connect cameras or accessories you use for your setup:

• PL3600218 adapter to connect cameras or accessories with T2 thread
• PL3600216 adapter to connect cameras or accessories with M48 thread
• PL3600225 adapter to connect accessories with SC thread
• PL3600242 adapter to connect cameras or accessories with M54 thread
• PL3600227 adapter to connect accessories with M57 thread
• PL8410001 2” visual back to connect cameras or accessories with 2” noise piece

 Please note: in order to be used, ARCO rotator has to be connected to ESATTO microfocuser or SESTO SENSO 2 focusing motor. ARCO is not designed as a stand alone unit.
