STEPHEN!
Did you notice the hint of the Encke Division in your Saturn pic!!! If the image is a little sharper, the Encke Division would be better resolved. But it's there, neat and unbroken on both sides!
Looks like you've got yourself a damn find Mak!!!
Not many pics of Saturn show the Encke Division, even from larger aperture scopes than your 7" Mak.
