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 adaptor for Takahashi FSQ-106 and to connect Takahashi photographic adaptors

In order to allow you to install ESATTO 4" in place of the original Takahashi focuser, we have designed a special adaptor that makes ESATTO 4" have the same thickness of the original focuser. In addition, we have created an adaptor 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 adaptors and you will find focus point with the same photographic adaptors you used before!
