Congratulations on your purchase of a high-quality Orion star diagonal. Your diagonal utilizes a
precision flat mirror with high-reflectivity coatings and top quality machined housings. Using a star
diagonal with your telescope provides a comfortable viewing angle for astronomical observation.
In addition, a diagonal is required to reach focus in many short-focal length refractors. The diago-
nal will work with refractors, Schmidt-Cassegrains, and Maksutov-Cassegrains, but not Newtonian
reflector telescopes.
How to Use the Star Diagonal
Remove the cover caps and place the barrel of the star diagonal directly into the telescope's
focuser. Secure it in place with the thumbscrew(s) on the focuser. Insert your eyepiece into the
of the diagonal and secure the eyepiece with the diagonal's thumbscrew. Notice there is a brass
compression ring inside the opening of the diagonal, interior to the thumbscrew. This ring prevents
the thumbscrew from marring the barrel of your eyepiece.
If you would like to adjust the position of the diagonal to accommodate observers of different
heights, simply loosen the thumbscrew(s) on your telescope's focuser, rotate the diagonal, and
re-secure your telescope's thumbscrew(s). Before rotating the diagonal, however, make sure the
thumbscrew on the diagonal is tightened, or the eyepiece may fall out and onto the ground!
The 2" star diagonal will accept either 2" or 1.25" eyepieces using the supplied 1.25" eyepiece
adapter. If using 2" eyepieces, remove the 1.25" adapter from the diagonal.
Focusing
Focus with your telescope's focusing knob. The 1.25" diagonal requires approximately 9cm inward
focus travel relative to the eyepiece's focus position without the diagonal. The 2" model will require
slightly more inward focus travel, as it requires approximately 11cm relative to the eyepiece's focus
position without the diagonal.
