There are accessories available that invert the image the 'right' way up; however, they are more appropriately used for viewing terrestrial objects rather than astronomical objects. To help the observer become familiar with inverted images of astronomical objects many astronomy books tend to show maps of the Moon and images of Planets with south at the top just as if they were viewed through a refractor. Refractors tend to be mainly used for solar system observing rather than deep sky observing such as Galaxies or Nebulae.
