    Features of the PrimaLuceLab SESTO SENSO 2


    Multiple Control Options

    It connects to the USB port of your EAGLE or Windows computer and gives you electronic focus control while maintaining an ability to be manually controlled if needed. You can also connect any smartphone or tablet to have wireless control through its integrated WiFi!

    Single Compact Design

    The housing is made up of a single block of aluminum, CNC machined, with an aesthetic red anodized finish. The upper part of the SESTO SENSO 2 is made up of rigid plastic in order to allow the WiFi antenna to operate for easier remote control.

    Dimmable LED Lights

    LED lights on the SESTO SENSO 2 body are dimmable and can even be turned off completely. Reduce light emission during astrophotography or visual use for better light management.

    ARCO Port 

    The SESTO SENSO 2 now comes with ARCO port to easily connect the ARCO camera rotator without the need for additional data or power cables. With ARCO, you can remotely control the rotation angle of your camera in order to achieve the perfect framing of the object you want to record.

    Self Centering Clamp (SCC) Function

    SESTO SENSO 2 can be installed on most focusers without the need for external brackets. Designed to fit to a 25 mm diameter shaft. Even if SESTO SENSO 2 is installed, you can use the manual knobs of your focuser.

No Backlash Adjustment

Beautiful product, easy to install and run. Lack of backlash setting can be problematic with autofocus routines. PrimaLuceLab has examples online of an ASCOM driver with backlash settings, but this does not exist in the ASCOM package provided by them. PrimaLuceLab support states they should have an ASCOM driver "with backlash settings and support for ARCO rotator in several months".

No Backlash Compensation

Beautiful, easy to install and calibrate, using with a Feathertouch focuser. Although earlier ASCOM driver had backlash settings, neither the Sesto Senso 2 software or current ASCOM has capability to adjust for backlash. This deficiency creates some problems with autofocus routines, especially with short focal length systems. Would gladly change review to 5 stars if this were corrected.

Great products and service...just slow

Service and support are excellent! Product selection is great. Product availability and delivery - and communication about status - not so good.

Works perfectly

I now have 2 of the Sesto v2 and 1 of the older Sesto v1 focus motors and they have worked perfectly for me for up to 3 years. I like the capability to adjust focus speeds, ramp rates, and holding power for various size camera weights. The newer version has improved easier focus shaft attachment and has a very solid mechanical connection
