    Troughton and Simms telescopes

    Attached are my measurements of field and power of the several scopes included with my purchase. Do these numbers make sense? The bottom is a Galilean. It has an internal stop which is not in the focal plane of the eyepiece, as it can't be, because of the negative eyelens. Maybe I have the eyepieces confused, but this seems to be the most logical permutation and combination of the many pieces I found.
    As you can see, the long tube (long fl objective) seems to accept the two eye tubes situated below, for clarity. One has a 4 wire reticle, the other has a 2 wire reticle. The powers of the assembled scope with these two eyetubes is indicated.
    Thanks
