The ESATTO 2" LP focuser with ARCO 2" rotator (PrimaLuceLab, SKU: PLLEST2LPARCO2 ) is an ultra-compact module combining the ESATTO 2" LP precision focuser and the ARCO 2" rotator. The set offers only ≈ 55 mm of total back-focus with 50.9 mm of free aperture, making it ideal for astrographs and telescopes with very limited focal length reserve. A single 12 V power supply and a single USB-C provide full remote control of camera focus and rotation from PLAY software or ASCOM/INDI drivers.
