PrimaLuceLab ESATTO 2" Adapter for SC Thread Telescopes

The ESATTO 2" is the perfect motorized focuser for Schmidt-Cassegrain telescopes such as the 8" and 9.25" Celestron SCT and EdgeHD 800 models. By adding the SC adapter, you can screw the ESATTO 2" focuser directly onto the thread SC back of these telescopes and use ESATTO to obtain a more precise focusing. The low profile of ESATTO leaves enough backfocus to use the EdgeHD or other focal reducers with SC thread.

Thanks to the ESATTO 2" adapter for SC threaded telescopes, you can add the ESATTO 2" focuser to SC telescopes like the Celestron, C6, C8, C9.25 and EdgeHD 800. In the image below, the Celestron C9.25 telescope with focuser ESATTO 2" and EAGLE control unit, installed in parallel with the optical tube. Since this adapter fits into the body of ESATTO 2", it does not add optical thickness to the ESATTO 2" that maintains its thickness of 67mm.

After ESATTO you can connect the thread adapter SC PL3600225 to connect the accessories with SC thread to ESATTO (for example the focal reducer for SC telescopes) or the eyepiece holder 50.8mm PL8410001 to connect chambers or accessories with adapter 50.8mm.
