The ESATTO 3.5" LP → Officina Stellare Veloce RH300 adapter (PrimaLuceLab, SKU: PL3600361 ) allows you to install a precise, remote-controlled ESATTO 3.5" LP focuser in place of the factory focuser of the Officina Stellare Veloce RH300 (f/3.4) fast astrograph. The collar uses the original mounting points of the rear tube plate, so the mount does not require drilling or other mechanical modifications, and the telescope's total back-focus remains in line with the manufacturer's specifications.

The most important features of the adapter

• dedicated fit for RH300 rear cell – quick plug-and-play installation
• maintaining the nominal back-focus of 65 mm – compatibility with reducers and correctors
• CNC milled 6061-T6 aluminum, hard anodized - high stiffness and corrosion resistance
• full internal diameter 86 mm – no vignetting for full frame matrices
• blackened and grooved interior – effective reduction of reflections, better contrast
