would fit the body of an orion eye piece. The orions look fatter that the Plossl. So I'm not sure and I can't see a need to spend much on the extension tube since it just holds everything together.

what you are looking at there is a T ring with a 1.25" nose piece. it is designed to go directing into the eyepiece holder without the need for an eyepiece. this is for taking images at the prime focus point, not imaging a projection in an eyepiece. you may need a 2" nose piece for your scope, not sure.
you have a pretty long focal length telescope there which will be pretty good for planetary work.
