Fits my televue ethos great

Perfect for making my pesky 8 inch ethos long enough for parfocal rings. Fits perfectly.

Perfect fit

It is not silver colored as shown in the picture, it is metallic shiny black. It has perfect fit, but I really wish that inside had matte flocking. Brought my Ethos 8 and 13 *roughly* parfocal with Ethos 21 and Nagler 31.

Made my Night vision gear work

I use a 55mm TeleVue plossl with my night vision monocular and was needing another inch of back focus. I actually have two 2 extensions on the eyepiece now and works like a cham. Threading is smooth and the weight in near nothing... Highly recommend

I bought this to experiment in building a CS mount and mate-up with a high def camera. It appears that with some machine shop work I will have a system that will allow me to stay warm in the winter nights.
