I saw this on Facebook but I have been aware of it for many many years.

Some will use the click method to centre a scope and wind the adjusters fully in then back out counting the clicks to get back to the other side then half the clicks to get to the centre . You may find if you go too far , you will find a little resistance but can still turn them till they stop and that may be too far and the erector tube will get stuck .

In this case a tap from a rubber hammer or a soft soled shoe , Yes a soft soled shoe should free it up.

Don't beat the scope up when doing it, a few taps should free it up.



Some scopes have a flat spring and some have a coiled spring for the erector tube. A cool sprung one often has a bit extending out if the scope at the bottom.

Looking at the scope in the video, it is inevitable that it will have a problem with sticking as the erector tube leaf spring is in the wrong place.

As seen in the view above in the video, it should be sitting at roughly the 4 o'clock position so it acts on the erector tube to push it both upwards and to the left. Sitting where it is a about 6 o'clock it isn't doing its job properly.

This would be the correct position of the erector tube spring - this view looking from the eyepiece side so it is at the 8 o'clock position and pushing up and to the right:
