DESCRIPTION

ET1-125.125

ET1 - Short 2" Extension Tube - $29

Provides 1 3/8" of additional focus travel to the rear. Uses compression ring.

ET3.125

ET3 - Deluxe 2" Extension Tube - $49

Provides an additional 2.26” of back focus. The 2” receptacle is 1.6” deep so if the item you are inserting is longer than 1.6”, add the difference to 2.26” to determine the actual amount of extension. Made in the USA on our HAAS cnc machines, this all aluminum extension tube has a rubber grip and uses a brass compression ring. The 2” insert tube has a 2” filter thread and is beveled which improves the snugness of the fit when the focuser lock screw is tightened. Works well with our FA2 1 1/4" adapter.

ET475.125

ET475 - Long 2" Extension Tube - $49

Same as ET3 above but provides a full 4.75" of extension. For use only with our binoviewing telescopes in place of a threaded extension for more convenience.
