Enhanced extension tubes include a compression ring and 48mm filter threads. Extension tubes are placed in the end of a drawtube to extend the current length of the drawtube. If you have replaced a focuser with a low-profile model, an extension tube may be required to reach focus. The Enhanced Extension Tubes from Jims Mobile include a compression ring for holding eyepieces and accessories without scratching the equipment. The adjusting screw presses against the ring which tightens around the eyepiece or accessory.
