There is nothing wrong. These scopes are Newtonian reflectors that normally provide inverted views–as 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° position to conveniently position the eyepiece for astronomical viewing.
Because of this 45° orientation, the images viewed through the OTA will be tilted when the scope is used to observe any terrestrial scenes.
