Just picked up a used Meade ETX90 for cheap.  Its got two built-in viewing ports, one on top at a 90 degree angle to the main lens, and one at the front, in line with the main lens.
 
When i put an eyepiece in the upper port, the image is reversed, ie, in order to view something to the right, I have to move the scope to the left.  The image is backwards.
 
Will a standard 45 or 90 degree prism diagonal fix this?
 
Thanks.
