PrimaLuceLab Focusers

PrimaLuceLab focusers cover two approaches to motorized focus. ESATTO robotic focusers replace the original focuser and come in 2", 2" LP, 3", 3.5" LP and 4" sizes, some combined with an ARCO rotator. SESTO SENSO 3 robotic focusing motors attach to an existing focuser instead.

The SESTO SENSO 3 SC version suits Schmidt-Cassegrain focus knobs, and the LS version drives telephoto lenses. All are designed for precise, repeatable focus in automated imaging.
