The M81 25mm extension tube can be directly threaded to the ESATTO 3" draw tube in order to attach cameras and accessories further away from the ESATTO robotic microfocuser. This is particularly useful for refractors which usually have long travel focusers. This M81 extension tube has 25mm thickness, is made of anodized aluminium, and has a M81 female on the camera side for connecting any of the ESATTO 3" camera adapters.
