ESATTO 3.5" LP focuser with ARCO 3" rotator (PrimaLuceLab, SKU: PLLEST35LPARCO3 ) is the smallest and lightest integrated focusing and rotation package in the PrimaLuceLab offer. It combines the ultra-low-profile ESATTO 3.5" LP focuser (body thickness 32 mm, free aperture 90 mm) with the precise ARCO 3" rotator (thickness 23 mm, resolution 1 arcsec/step). The whole thing together with the dedicated adapter takes up only ~55 mm of back-focus, making this set ideal for astrographs with very short focal reserve.

The most important features of the set

• ESATTO 3.5" LP - 90 mm free aperture, 10 mm travel, 0.01 µm/step resolution, 10 kg payload
• ARCO 3" - 0-360° continuous rotation, 1 arcsec/step resolution, 76.3 mm free aperture
• Low total thickness - focuser + rotator + adapter ≈ 55 mm back-focus
• One power supply and one USB-C - the rotator takes power and control signal directly from the hoist; fully supported by PLAY, ASCOM and INDI
• Built-in Wi-Fi (Virtual HandPad) - remote control from a browser without additional software
• Play-free mechanics - Crayford supported by ball bearings, steel drive rail
• PLUS system - M6 threads in the body facilitate the assembly of clamps and PrimaLuceLab accessories
