If you can move/and/or store that chunky great mount, I would have thought the difference in length of the two scopes would be insignificant. You might also get frustrated before too long with the lack of focal length for smaller objects.

Appreciate the advice thank you. I'll stick with the 80ED for now and see how it goes.
If I don't like it I can repurpose it as a guide scope.
