THE STAR DIAGONAL (Refracting Telescopes Only)

The erect image diagonal attaches to the back of a refracting
telescope and contains a small prism that reflects light at a 90° angle,
providing a more comfortable viewing position Most astronomical
telescopes will give a view that is either inverted or reversed left-
to-right The erect image diagonal corrects the image so that you
will have a 100% correctly oriented image, making your telescope
perfect for daytime terrestrial observing
To insert the diagonal:
1 . Remove the caps from both sides of the diagonal
2 . Loosen the setscrews on the back of the focuser and pull out
the small dust cap
3 . Insert the smaller tube on the diagonal into the back of the
focuser and secure it by tightening the setscrews You can
adjust the angle of the star diagonal to any desired direction
before tightening the screws
NOTE: An erect image diagonal is not able to reach focus on a Newtonian
telescope. The image in a Newtonian telescope will always appear upside-down.
