So the scope by itself weighs ~3?

Yours is close to my setup. Let me ask a use example query: Starting with the scope set up in park position with the tube rotated so the focuser is pointed west and the finder is on the south. When you go to polaris I assume the finder would be on top (also assuming you can see polaris from your location). Now if you slew to some southern oriented target does the cube rotate to keep the finder on top or is the finder now in some awkward unusable position?

Appreciate the help - this is still my primary choice if it will work.
