TPO 80mm Extension Tube - 2"
Do you need a little more "space travel" in your focusing? If you've ever had to pull an eyepiece barrel out to the very end, or precariously balance and accessory to get it to come into focus, then worry no more. OPT has the solution!
With the TPO 80mm Extension Tube, you can simply insert your favorite 2" eyepiece, accessory or 2" to 1.25" adapter and instantly get over 3" of additonal "travel" to help you come to focus. We have these extenders custom machined and fitted with a non-marring brass compressing ring that won't mar your good eyepieces!
