PrimaLuceLab 3" visual back for ESATTO 3" and ARCO 3"

If you want to connect a camera with a 3" nosepiece to your PrimaLuceLab ESATTO 3" or ARCO 3", just connect the 3" visual back to the M81 thread of ESATTO 3" or ARCO 3". This adapter has an internal brass compression ring to avoid scratching the inserted nosepiece as well as 3 locking screws (120° separation) for a perfect fit, even for heavy cameras or accessories.
