That's why, instead of using a normal 2\" visual back, ESATTO 3\" offers a M81x1 male thread and, through a complete series of optional camera adapters with stop ring, it allows you to directly connect the most common DSLR, mirrorless and CCD or CMOS cooled cameras directly at the focuser. The stop ring allows you to lock the camera at a precise angle to better frame the object to be photographed. The stop ring adapters are available in many different sizes: this way you can connect, with maximum rigidity and comfort, any camera or accessory.
