About this product

Model:  pl_sesto_senso
Part Number:  SESTOSENSO

Includes set of 5 bushes for different focusers. 

PrimaLuceLab Sesto Senso robotic focusing motor for your telescope!

Clever design means motor and the control electronics are together in a compact metal box (dimensions 87 x 60 x 43mm). 

Replaces your focuser's micrometer knob.

Connecting it to your computers USB port enables you to remotely control focus with high precision (0.7 microns!) without vibration. 

The supplied software and ASCOM driver provides a number of advanced features, useful for astrophotography. 

Compact, lightweight and integrated design

Sesto Senso has 3 ports. In the picture below, to the right you see the 12V power supply port that powers the motor and integrated electronics. Using the power cable provided in the package, it can be powered by a common 12 volt cigarette lighter socket. At the centre you see the USB connection port that connects Sesto Senso to a computer, using the provided cable. To the left you see the port for connecting the optional temperature sensor and allowing you to perform auto focus adjustment procedures with the ambient temperature variation.

 

ASCOM driver and configuration software

Sesto Senso has been designed for astrophotography and provides all functions with commands useful for even the toughest pictures. It comes with Sesto Senso software that allow you to control the focuser and ASCOM drivers, so you can use it with the most popular astrophotography software such as BackyardEOS, BackyardNikon, MaximDL, FocusMax, Voyager, Sequence Generator Pro and others. If the recording software supports more focusers, you can also use more Sesto Senso at the same time.

At present Mac support is more limited. Users of The SkyX Pro can use the Sesto Senso with a third party driver and there is an INDI driver available for Stellarmate users.

Sesto Senso software allows you to adjust various advanced settings:

  • Movement speed and acceleration/deceleration ramps
  • Motor torque to increase the focuser weight load capacity of the camera when the focuser is stationary
  • Moving and positioning test with reading of steps number
  • Selection of pre-settings for low, medium and heavy loads
  • Reading of stored settings in the internal electronics
  • Reading of temperature (requires optional temperature probe)

Compatible with many focusers

Thanks to its special design, the Sesto Senso robotic focusing motor is compatible with many focusers by using the bushing kit supplied in the package. You just have to choose the right bushing for your focuser and install Sesto Senso, it's very simple! Another advantage of the design is to be able to easily move Sesto Senso from one telescope to another. If you change telescope, you can easily connect Sesto Senso to your new instrument!

Set of 5 bushings for various focusers:

  • Red bushing Ø2.5mm for AIRY refractors (ED72, APO80, ED90, ED100, APO104T, APO120, APO150T), OrionOpticsUK VX and CT, Baader Steeltrack® focusers, TS-Optics V-Power, Omegon V-Power and Skywatcher
  • Black bushing Ø2.8mm for Feather Touch focusers
  • Green bushing Ø3.5mm for Takahashi telescopes
  • Silver bushing Ø3.1mm for Moonlite focusers
  • Yellow bushing Ø4.0mm for AIRY refractors (APO 65F, BLACK 80T) and SharpStar telescopes with 2" focusers

Primaluce Lab Sesto Senso Sixth Sense Robotic Stepper Focus Motor

I get this focuser motor to use it with my Esprit 150, I fitted it easily on the fucuser and it works just fine. The focuser feels high quality and well made and easy to use, it comes with nice software and ASCOM driver which means that it can be controlled via lots of applications such as Kstars, SGP, and others!
Although it is a bit pricey but I really like it and would deferentially recommend it.

Stylish design with good performance
Tuesday, 23 April 2019  | 

I have been gradually updating my AP kit so that I can spend less time imaging in the cold outdoors and more time viewing from the PC screen indoors. Being able to remotely focus was an essential element and so i was looking for something to attach to my small refractor (WO Megrez 72). FLO recommended the Sesto Senso which, although a bit expensive, looked like a more stylish and modern solution than some of the other 'Heath-Robinson' options on the market. The focus motor arrived from FLO in a few days and I was able successfully to attach it to my scope without too much difficulty. The main things to be aware of are (a) the grub screws are small and can be a bit fiddly, and (b) although there are a range of couplers included to match different size focuser shafts, unless the coupler hole is exactly matched to the shaft then you may need to adjust the setup a few times to get the motor and focuser shafts perfectly concentric (ideally to allow adjustment there would be 4 screws to attach the focuser rather than just 2).

From a software control perspective the Sesto Senso was very straightforward to set up, I use it with SGP via the Ascom drivers and so far (1 month in) it works perfectly on my rig. One small annoying feature: there is a white semi-opaque plastic top to the unit with a red light which flashes underneath when in use and can be a bit distracting in the dark. The other point to note is that I needed to balance my scope along the third axis after fitting the motor to counterbalance the weight hanging off one side.

Overall I am very happy with the performance of the unit, it only dropped 1 star in this review because of the value for money equation - though I see that FLO have now reduced the price which makes it an even more attractive option.

Very nice design and manufacture at a competitive price
Tuesday, 19 February 2019  | 

I have been looking for sometime to provide a stepper motor drive for my first generation Explore Scientific ED102 which has a reasonable Rack and Pinion focuser. Up to now the options seem to be either expensive and convoluted (requiring a new focuser plus special adaptor etc.) or a bit 'Heath Robinson'. This new product caught my eye. The standard adaptor clamp for the SESTO SENSO is 25 mm in dia. I removed the focusing knobs from the ES 102 and measured the diameter - seemed to be about right (but the ES 102 is not in the list of compatible scopes). When it arrived from FLO, I found I had to carefully file away about 30 thou from part of the clamp in order to get it to fit snugly.

Now it's fitted it works a treat! Software installs without problems and is easy to use (although I have not tried the ASCOM driver yet). I am very pleased with the product - it is nicely designed and made, and easy to disassemble if needed. For me it is a much better solution than the alternatives.
