The JMI Telescopes 2" Standard Extension Tube adds 2.5" (~64mm) of optical path length to your telescope combination, and is useful for retaining the optical path length when replacing a star diagonal or a prism with a shorter accessory, such as a photo adapter.  It uses a pair of standard set screws to affix your 2" accessory.  A JMI Extension Tube also reduces your minimum focusing distance, allowing closer observation of subjects when focus is moved out by eyepiece projection, use of a Barlow lens, etc.

Made in the USA.
