PrimaLuceLab ESATTO Robotic Focusers

PrimaLuceLab ESATTO robotic focusers replace the telescope's focuser with a motorized unit for precise, repeatable focus in automated imaging. Sizes run from the ESATTO 2" and 2" LP low profile to the 3" and 4" microFocusers and the 3.5" LP, with versions combined with an ARCO rotator.

A large set of adapters, stop ring adapters, extension tubes and visual backs fits ESATTO to specific telescopes, from the Takahashi FSQ-106EDXIV to the PlaneWave DeltaRho 350 and GSO Ritchey-Chretien tubes.
