ESATTO 2" micrometric focuser

Often refractors are provided with focusers suitable only for visual use but not for imaging. In fact, during long exposures required in deep-sky astrophotography, you have to keep the sensor perfectly in the focus point avoiding focuser that moves camera sensor out of focus. For this reason Borg fluorite apochromatic refractor 55FL f3.6 comes with ESATTO 2" microfocuser that offers high load capacity, great focusing precision without backlash! The focuser has a rear M57 thread to connect cameras by adding the proper photographic adapter.
