Nothing is wrong. These scopes are Newtonian reflectors that normally give inverted views. They are designed for astronomical use.
On the SLT reflector telescope tubes (OTAs), there is a metal bar (the dovetail bar) that is used to hold the tube to the mount arm. The bar is attached to the tube at a 45-degree position to conveniently position the eyepiece for astronomical viewing.
Because of this 45-degree orientation, the images through the OTA will be tilted when the scope is used to view any terrestrial scenes.
