Product Details

  • Have you ever wished your 2" eyepiece barrel was just a little longer? For those of us who use eyepieces in different focal length telescopes frequently, we often encounter the problem of needing more focus travel for certain eyepieces. A time-honored remedy has always been to simply pull the eyepiece out of the focuser as far as it will go... But there are times when it isn't far enough.

    With the Tele Vue EBX-2120 Extension, you can now add another 2" onto any Tele Vue threaded 2" eyepiece barrel. Just twist it into place just like you would a filter... and enjoy the fact that the extension is also threaded for a filter!

    If you use different eyepieces with different focal lengths as you view, there is a time when the barrel of one may not have enough length. Now you can simply add this extender to help you achieve proper back focus.

Barrel Extender

To bring my video camera to focus on my Dob, I use a shortened set of truss poles. Now with the barrel extender, I can also use my 13mm Ethos. I have the best of 2 worlds-a set up for both video and visual viewing without having to switch truss poles.

Excellent barrel extender for focusing telescopes requiring backfocus

This solved the problem of bringing telescope images to focus with my TeleVue 2 inch eyepieces on a refractor.

EBX 2021 Extension

The product details state, "... you can now add another 2" onto any Tele Vue threaded 2" eyepiece.." I didn't really expect this extension to add another 2' to my eyepiece, but was hoping it would. It does add 1 3/16" which is really all I need.

Not for any 2" eyepeice barrel

Beware - the thread on this adapter is for tele-vue eyepieces ONLY. The thread is not the same as a standard 2" eyepiece filter. I just bought 2 of these and after about 1 turn, the threads lock up. Seems they are the same OD but slightly different pitches. Will be returning. I'm sure if you have a TV eyepeice it'd be great. But the description could have used more clarification. 3 stars. Product not defective, but description misleading.
