Celestron Zoom Eyepiece

[Nike]

Can anyone advise pls, bought a Celestron Zoom eyepiece 24mm / 8mm in the summer, was a bit tight when you zoom up or down and you had to hold the diagonal  but being new thought it would slacken up. Have been using recently and is still very stiff and not enjoyable to use, my friend has one and slides up and down with ease. Have been zooming in and out in the house to loosen it up dozens of times by hand not attached to scope but still tight. Anyone any ideas how to slacken off. With hindsight should have sent back but now it is now 4 months later......thanks.

The top of the EP screws off .

U can see the mechanism

inside. Mine is the same.

Cold weather, & it is very stiff.

I smeared a drop of oil on

the inside .Be very careful  

when doing this.
