I have considerable expereince with high power telescope for bird watching. An angled scope allows you to look up at a higher angle and it's quite easy to get on target with a bit of practice. One solution is to tape a small tube - even a piece of drinking straw - along the side of the scope. View a fixed object through the scope and then align the tube on the same object. Then when you need to find anothe object simply line up the viewing tube and slook through the scope. It really does work.
