Don't they have to fit somewhere between the ocular and objective lenses which would mean dismantling your scope.
OR.
Is there another type ?

I think they fit at the ocular end and have a built-in eyepiece, Chas.
They're normally 1 1/4" fit (for telescopes) and are commonly 2x.

I thought you had to remove the ocular (eyepiece, whatever) then install the Barlowe and then re-install the eyepiece, at least that's what you do with telescopes, but on camera's it goes just behind the objective, I think.
I tried quite a few years ago to make an extended eyepiece that would go over the ocular lens of a scope, so that you could move the scope forward on it's rail and at night remove the extended eyepiece and fit an NV mono which would have the same eye relief from the actual scopes ocular, therefore ridding us of the compromised head position associated with fitting NV mono's.
It didn't work

They became quite popular in the benchrest community in the 10.5 lb class . There were no light weight high magnification scope available at that time . Some resourceful soul found a suitable lens and fit it to a 10x scope and it worked quite well . The factories soon recognized the market and the light weight big power scopes soon ruled the light rifle classes . I was hoping someone here had taken a shot at it .
