ESATTO (EXACT) 4" robotic micro focuser!
The ESATTO 4" is the large dimensions robotic microfocuser that we designed for observatory class telescopes or for astrographs that need for large free aperture, like the Takahashi FSQ-106. Compared to the smaller models, ESATTO 4" offers a larger free aperture of 102mm, a longer draw tube travel of 35mm and a higher payload capacity of 10 kg, always with the incredible technical features of all the ESATTO focusers: incredible resolution of 0.04 microns per step, USB-C port for computer control, WiFi connection with included Virtual HandPad and ARCO rotator port.

The ESATTO 4" is the largest robotic microfocuser in the ESATTO family and, thanks to the large 102mm free aperture and high 10kg payload capacity, it's perfect for large professional telescopes usually found in observatories or for astrographs offering a large corrected image circle that require the use of focusers with large free aperture, like the Takahashi FSQ-106.

- Crayford style focuser with 40 ball bearings, specially designed for very high load capacity (up to 10 kgs) with no flexure

All-in-one design for the best performance also with professional telescopes

The perfect focuser for Takahashi FSQ-106 astrograph
Thanks to special optics, Takahashi FSQ-106 is one of the best performing astrographs and it's used by the best astrophotographers in the world. The special internal corrector is so large that ir requires a very large focuser to use it. For this reason ESATTO 4" is the ideal focuser for the Takahashi FSQ-106 telescope thus allowing remote and high precision control even of very heavy cameras and accessories.

Special adapter for Takahashi FSQ-106 and to connect Takahashi photographic adapters
In order to allow you to install ESATTO 4" in place of the original Takahashi focuser, we have designed a special adapter that makes ESATTO 4" have the same thickness of the original focuser. In addition, we have created an adapter to be screwed to the M110x1 thread of the ESATTO 4" draw tube to convert it into an M92x1 female thread which is the same as the one on the original Takahashi focuser. In this way you can remove the original focuser, install ESATTO 4" with the optional adapters and you will find focus point with the same photographic adapters you used before!
