- PLUS rings offer a better stability, avoid flexures and let you connect dovetail bars, guide rings, clamps and the EAGLE
SESTO SENSO 2: the most advanced robotic focusing motor!
This special version of the TS-Optics 71SDQ 71mm f/6.3 four-element apochromatic refractor adds SESTO SENSO 2 - The highly accurate, advanced, vibration free, robotic focusing motor for your telescope! Connect it to the USB port of your EAGLE or Windows® computer to electronically control focus while still allowing you to manually move your focuser by hand if needed. If you don’t want to focus using a computer, you can connect wirelessly from any smartphone or tablet using the integrated Virtual HandPad via the built-in Wifi network in the SESTO SENSO 2! Thanks to the Self Centering Clamp technology (SCC), SESTO SENSO 2 can be installed on most focusers without the need of external brackets. The supplied FOCUS Manager software and ASCOM driver allow easy configuration of the many advanced features of SESTO SENSO 2. Thanks to the precisely controlled motor with integrated electronics, SESTO SENSO 2 achieves incredible precision of just 0.7 microns. And you can also expand SESTO SENSO 2 features by adding the ARCO robotic camera rotator!
TS-Optics 71SDQ 71mm f/6.3 four-element apochromatic refractor with SESTO SENSO and the following optional accessories: Vixen style 140mm PLUS dovetail bar (below the tube), EAGLE with guide scope in parallel (above the telescope).
TS-Optics 71SDQ 71mm f/6.3 four-element apochromatic refractor with SESTO SENSO - photographic use:
The 2,5" focuser has a standard 2" visual back and M63x1 thread.

ESATTO as focuser for refractors and astrophotography
Thanks to the many available adapters, you can easily use ESATTO as the new focuser for refractors and improve performance, especially in astrophotography. Refractors, and especially the apochromatic models, are perfect instruments for astrophotography since they haven't a very long focal length (you can use them for very long exposures also with affordable mounts) and they combine very good performance with easy of use. But many refractors use a focuser that may not be able to adequately support your camera and the accessories used in astrophotography: let's see how you can improve your refractor telescope by replacing the focuser with ESATTO.
