They are different focal lengths for one thing and the nodal point for each will be different won't it? Or do I have this wrong?

I've never done any real panos so I don't have any experience with it but consider the distance. The parallax of our nearest star can be done in the back yard over a 6 month period as we have the Earths orbit as a baseline. Having two telescopes let's say, one metre apart, does not have the resolution to be able to detect parallax. If it did, any star in our stellar neighbourhood would not be registerable from one minute to the next due to its movement due to the Earths orbit and close stars moving against the stagnant background.
