• The Celestron Focus Motor for SCT enables electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing.
• Self-powering: When connected to a Celestron computerized mount, the mount provides the power. When connected directly to a computer, USB provides the power.
• Compatible with a wide variety of Celestron Schmidt-Cassegrain, EdgeHD, and Rowe-Ackermann Schmidt Astrograph optical tubes. Check description for full list.
• Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation.
• Focuser Utility software for Windows provides a simple user interface. Also compatible with Celestron PWI.
• Enables autofocusing with a camera and third-party software via ASCOM.
• Indexed focus position allows the motor to automatically return to a previous focus position and prevents the focus motor from reaching the end of telescope’s mechanical focus travel.
• Now compatible with the 9.25” EdgeHD.

The Focus Motor provides electronic focusing for Celestron Schmidt-Cassegrain (SCT), EdgeHD, and RASA telescope optical tubes. With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescope’s hand controller or a computer instead of using the focuser knob. A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and a must-have accessory for astroimagers. With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. Combined with computerized control of the mount and camera, the focus motor enables the imager to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design.

Compatible Optical Tubes

The focus motor is compatible with all SCTs from 6” to 14” in aperture that have been produced since the year 2006. It is not compatible with 5” SCTs or older models. It is compatible with the 8” Rowe-Ackermann Schmidt Astrograph (RASA),  the 36cm RASA, the 7” Maksutov-Cassegrain, and all the EdgeHD optical tubes. The RASA 11 (91075) is compatible with the #94155-A focus motor, but requires the Focuser Retrofit Kit for RASA 11. The RASA 11 V2 (91076) is compatible with the #94155-A without a retrofit kit needed.

For 6” Schmidt-Cassegrain telescopes only, the Off-Axis Guider (#93648) cannot be used when the focus motor is installed due to mechanical interferences.

SESTO SENSO is the best robotic focusing motor for your telescope! Compatible with most focusers, install it in place of the micrometer knob and connect it to USB port of the EAGLE or Windows computer to remotely control without vibration and with high precision your telescope’s focuser!

The supplied software and ASCOM driver allow you to easily set up many advanced features of SESTO SENSO, especially useful for astrophotography.

Thanks to the precise control motor with integrated electronics, SESTO SENSO achieves incredible precision of just 0.7 microns!

Thanks to clever design, PrimaLuce Lab engineers have created the SESTO SENSO robotic focusing motor for telescopes, incorporating all the elements usually outside in normal motorised focusing systems.

Systems consisting of a motor with separate control box and connecting cables are the past, SESTO SENSO encloses in a compact metal box (dimensions 87 x 60 x 43mm) both the motor and the control electronics.

All with the great design PrimaLuce Lab create for all its products.

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 cigarette lighter socket. Alternatively, an optional cable is also available to power it directly from the EAGLE. At the center you see the USB connection port that connects SESTO SENSO to EAGLE or to another control computer, using the cable provided in the box. 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.

Compatible with many focusers

Thanks to careful design, SESTO SENSO robotic focusing motor is compatible with many focusers, due to 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 our design is to be able to easily move SESTO SENSO from one telescope to another. If you change telescope, you can easily connect SENSO SENSO to your new instrument! Compatible models:

– Hybrid-Drive focusers of PrimaLuceLab AIRY refractors (ED72, APO80, BLACK 80T, ED90, ED100, APO104T, APO120, APO150T)

– Focusers of Orion Optics UK VX and CT

– 2″ and 3″ focusers of GSO RC telescopes

– Crayford focusers of SkyWatcher ED80, ED100, ED120 and Newton f/4 – f/5 telescopes

– Baader SteelTrack focusers

– Moonlight focusers

– 2″ Feather Touch focusers by Starlight Instruments

– 2,5″ and 3″ Feather Touch focusers by Starlight Instruments (by adding the optional 33mm adapter)

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. 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)

• deluxe focuser with index marks for fine focusing of CCD cameras and eyepieces
• 2 screws fix the focus position
• M48 x 0.75 female thread on the telescope side and M48 x 0.75 male thread on the camera side
• you also can use the focuser as a variable M48 (51mm to 91mm) extension

A true helical focuser like this TS Helical Focuser, works like a camera objective… when you turn the focusing ring, neither the lens nor the camera (or eyepiece and diagonal) rotate – The only motion is in and out.

The advantage of this helical focuser is the fine adjustment possible, in part due to the fine pitch of the focusing ring’s thread, and in part due to the large diameter of the ring.

In the case of the TS Helical Focuser, virtually backlash-free movement and graduated markings on the focuser allow repeatable return to the focus point simply by noting the focus position reading.

Features

• no rotation of the diagonal or camera – motion is only in and out
• wide focus range … 51mm minimum height / 91mm maximum height
• simple adaption to the telescope tube with the M48 x 0.75 (2″ filter) thread
• good solution for self build
• simple adaption to camera and / or eyepieces
• wide free aperture of 45mm
• also good for use as a variable M48 extension (51mm to 91mm)

The Helical focuser has a wide focusing range of 40mm. The focuser is very short, the minimum heigh is 51mm. So you can use the focuser on telescopes or tele objectives with reduced back focus.

Specifications:

• non rotating helical focuser with index marks and fixing screws
• connection thread on the telescope side … female M48 x 0.75 thread (2″ filter thread)
• connection thread on the camera side … male M48 x 0.75 thread
• minimum height … 51mm
• focusing range … 40mm
