Gary,
Linked is a picture of a SNO-M and its telescope. Only one is provided, a Keplerian (inverting)6 x 30 scope. Notice that the rising piece permits the scope to be collimated, unlike the rising piece on your scope. It is the same 6 x 30 scope provided with the SNO-T, which also has a Galilean (erect view) scope.
I am told it is possible to amputate most of the tube of the inverting scope and fit a negative lens to the eyepiece to obtain a Galilean, but the magnification has to be quite high, as otherwise one runs out of sufficient parallel tube.
